A composite function exists as a function that depends on another function. A composite function exists formed when one function exists substituted into another function.

The value of f(f(f(x))) is 1/x

In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.

Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.

A function that depends on another function is referred to as a composite function. When one function is inserted into another, a composite function is produced. For instance, f(g(x)) is the composite function created when x in f is replaced with f(x). f(g(x)). You can interpret f(g(x)) as "f of g of x."

Let the given function be f(x) = 1/x

f(f(x)) = f(1/x) = 1/(1/x)

simplifying the above equation, we get

f(f(x)) = f(1/x) = x  

f(f(f(x))) = f(x) = 1/x

Therefore, the value of f(f(f(x))) = f(x) = 1/x

Answer:

Step-by-step explanation:

Slope:

Rise: The difference between the y -coordinates of the two points is called the rise.

Run: The difference between the x-coordinates of the same two points is called the run.

First plot two points on the line.

(0, 6 )  and (4 , 0)

Rise = 6 - 0 = 6

Run = 0 - 4 = -4

[tex]\sf \boxed{Slope = \dfrac{Rise}{Run}}[/tex]

          [tex]\sf =\dfrac{6}{-4}\\\\=\dfrac{-3}{2}[/tex]

Answer:

Step-by-step explanation:

The range of the function is the set of all y- values.

The range on the graph can be determined by minimum and maximum points if the graph is continuous.

Looking at the given graph we observe:

The range is:

The number 102 in the sequence will be closest to 100.

A sequence in which each next term gets increased or decreased from the preceding by a constant value is called an arithmetic progression.

The difference of any two consecutive terms in an arithmetic progression is called the common difference of the AP (arithmetic progression).

Here each terms increases by 8. So, the common difference d is 8.

The first term is given to be 38.

So our sequence will be,

38, 46, 54, 62,...

nth term in an AP can be calculated by using the formula,

aₙ = a₁ + (n-1)d

To find the term nearest to 100,

100 = 32 + (n-1)8

68/8 = (n-1)

9.5 = n

But the value of n can not be a non-integer,

So the term nearest to 100 will be 9th or 10th term.

a₉ = a₁ + (9-1)d

a₉ = 8 + (8 x 8)

a₉ = 94

and,

a₁₀ = a₁ + (10-1)d

a₁₀ = 8 + (9 x 8)

a₁₀ = 102.

We can see,

a₁₀ = 102 is closest to 100.

Hence, 10th term is closest to 100.

The probability that the next type of stir fry ordered is shrimp is 0.28.

Given that, the frequency table provided summarizes yesterday's orders at Sizzlin' Skillets.

A frequency distribution table displays the frequency of each data set in an organized way. It helps us to find patterns in the data and also enables us to analyze the data using measures of central tendency and variance. The first step that a mathematician does with the collected data is to organize it in the form of a frequency distribution table. All the calculations and statistical tests and analyses come later.

The given frequency table is

Type of stir fry         Number of orders

Vegetable                       333

Chicken                           666

Pork                                 222

Beef                                 222

Shrimp                             555

As we know, probability of an event = Number of favourable outcomes / Total number of outcomes

Here, the number of favourable outcomes = 555

The total number of outcomes = 333+666+222+222+555 = 1998

So, the probability of getting shrimp = 555/1998

=0.277≈0.28

Therefore, the probability that the next type of stir fry ordered is shrimp is 0.28.

The the vertices if the triangle is reflected over the y-axis and then dilated by a scale factor of 2 wii be A'(4, 6), B'(0, 0) and, C'(-2, 4).

According to the given question.

The vertices of a triangle ABC are A(-2, 3), B(0, 0), and C(1, 2).

As we know that,

The rule for reflecting a triangle over the y axis is to negate the value of x-coordinate of each point, but leave the y-value the same.

Therefore, the vertices of triangle ABC when it is reflected over y-axis are

A'(2,3)

B'(0, 0)

C'(-1, 2)

Also, when the triangle is dialated by a scale factor 2 then the vertices will be

A'(4, 6)

B'(0, 0)

And, C'(-2, 4)

The required measure for the supplementary angles EB is calculated as 126°.

Given that,
Two supplementary angles are given ZA and ZB.
ZA = 2x - 20 ; ZB = 3x + 15

To determine the measure of ZB.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The sum of the supplementary angle is 180°.
ZA + ZB = 180°
2x - 20 + 3x + 15 = 180
5x - 5 = 180
5x = 180 + 5
5x = 185
x = 37
Now,

The growth factor for the annual rate of change +0.1 % is 1.001.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = + 0.1% = + 0.1 / 100 = + 0.001

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (+0.001)

B = 1.001

Now, the value of B is greater than 1 therefore, the corresponding growth factor is 1.001.

Using simultaneous equations in two variables we get that the cost of laminate is $ 0.65 per sq. feet and the cost of carpet is $ 4.12 per sq. feet.

Equations in algebra that involve two or more variables simultaneously, such as x and y, are referred to as simultaneous equations. The equations are referred to as simultaneous equations since they are solved simultaneously. There are countless possible solutions to just these equations.

A set of finite equations for which common solutions are sought makes up a system of equations, often known as an equation system.

Let the cost per sq feet of laminate be x and the cost per sq feet of carpet be y.

Now it is given that the cost of 750 sq feet of laminate and 525 square foot of carpet is $2717.25

∴ 750x+525y=2717.25

Again  the cost of 100 sq feet of laminate and 75 square foot of carpet is $374.75

∴ 100x + 75 y = 374.15

Now we solve the pair of simultaneous equations to find the value of x and y:

Multiplying the second equation by 7 and subtracting from the first we get:

750x + 525y =  2717.25

600x + 575 y = 2619.05

150x = 98.20

or, x = 0.654...

Substituting this  value in the first equation we get:

y= 4.115...

Therefore the solution of the simultaneous equation is:

x = $ 0.65 and y = $ 4.12

Therefore  the cost of laminate is $ 0.65 per sq. feet and the cost of carpet is $ 4.12 per sq. feet.

Step-by-step explanation:

what form should the equation have ?

I assume slope-intercept

y = ax + b

"a" being the slope, "b" being the y-intercept (the y value when x = 0).

but since we have the slope and a point, we can start with the point-slope form and transform it :

y - y1 = a(x - x1)

"a" is again the slope, (x1, y1) is the point.

so,

y - 7 = -5/3 × (x - -3) = -5/3 × (x + 3) = -5x/3 - 5

and therefore

y = -5x/3 + 2
