Let f(x)=x+5 and g(x)=x²-25 . What is the domain of f/g(x) ?
(A) All real numbers (B) All real numbers except 5 (C) All real numbers except -5 (D) All real numbers except -5 and 5
A composite function exists as a function that depends on another function. The value for f/g(10) is 1/5
What is meant by composition function?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.
Let the two functions be f(x) = x+5 and g(x) = x²-25
A function exists described as a relationship between one variable and another variable.
(f/g)(x) = f(x)/g(x) = (x+5) / (x²-25)
The domain of a function exists the set of all possible inputs for the function.
When the denominator is zero, the function remains undefined.
Hence, x cannot take the values 5 and -5.
The function (f/g)(x) is defined for all values of x except x = 5, -5.
Hence, the domain is all integers except x = 5, -5
⇒ (f/g)(10) = (10 + 5) / (100 - 25)
simplifying the above equation, we get
⇒ (f/g)(10) = (15) / (75)
⇒ (f/g)(10) = 1/5
Therefore, the value of (f/g)(10) is 1/5.

what is ∠ABD, ∠CBD, and ∠ABC??
The measure of angle ABD (m ∠ABD) is 44°
The measure of angle CBD (m ∠CBD) is 44°
The measure of angle ABC (m ∠ABC) is 88°
From the question, we are to calculate the measures of the given angles
From the given, information, we have that BD bisects ∠ABC
Thus,
m ∠ABD = m ∠CBD
From the given diagram,
m ∠ABD = (6x + 14)°
and
m ∠CBD = (3x + 29)°
Then,
(6x + 14)° = (3x + 29)°
Solve for x
(6x + 14)° = (3x + 29)°
6x + 14 = 3x + 29
Collect like terms
6x - 3x = 29 - 14
3x = 15
x = 15/3
x = 5
Put the value of x into the equations
m ∠ABD = (6(5) + 14)°
m ∠ABD = (30 + 14)°
m ∠ABD = 44°
Since
m ∠ABD = m ∠CBD
Then,
m ∠CBD = 44°
and
m ∠ABC = m ∠ABD + m ∠CBD
m ∠ABC = 44° + 44°
m ∠ABC = 88°
Hence, the m ∠ABD = 44°, m ∠CBD = 44°, and m ∠ABC = 88°

A function f is bounded above if there is some number B that f(x) can never exceed. The exponential function base e shown here is not bounded above. Is the logarithmic function base e bounded above? If so, find a bounding number. If not, explain why.
According to the question, the function f(x) is bounded with constant number. And the exponential function base e is not bounded. Similarly, logarithmic function base e is also not bounded.
Bounded values can be calculated with the help of asymptotes namely, vertical, horizontal and oblique. The vertical, horizontal and oblique asymptotes are constant values which grows the values of the function f(x) without bound.
A basic logarithmic function is a function with no horizontal shift as well as no vertical shift. All logarithmic function passes through a constant points and touches the horizontal axis which results into asymptotes. It either increases from left to right, or decreases from left to right.

Range of the function be {y ∈R, y ≥ −7}
What is an inverse function's domain and range?The domain of a relation's inverse is the same as the range of the original relation.
In other words, the y-values of the relation are the inverse's x-values.
Domain of f(x) = {x ∈ R, x ≥ −7} and Range = {y ∈ R, y ≥ 0}
Domain of [tex]f^{-1}[/tex](x)= {x ∈ R}, Range = {y ∈ R, y ≥ −7}
The domain of the function would be all x, such that x+7 ≥ 0, or x ≥ −7. Hence it is {x∈ R, x ≥ −7}.
Consider the range of the function y = √x + 7.
Since √x+7 ≥ 0, it is obvious that y ≥ 0.
Range would be {y ∈ R, y ≥ 0}
The inverse function would be [tex]f^{-1}(x)[/tex] = x² - 7
The domain of the inverse function is all real x, {x ∈ R}
For the range of the inverse function solve y = x²-7 for x.

Suppose the path of the jump changes so that the axis of symmetry becomes. X=2 and the height stays the same. If the path of the jump also passes through the point (5,5) , what quadratic function would model this path?
The quadratic function of the jump is y = -0.22x^2 +0.89x + 6.11 if the jump changes so that the axis of symmetry becomes X=2 , the height stays the same 7 and also passes through the point (5,5)
Quadratic function involving vertex is given by
y = a(x-h)^2 + k
Where (h,k) is the vertex which is given as (2,7)
y = a(x-2)^2 + 7
y = a(x-2)(x-2) + 7
y = a(x^2 -4x +4) + 7
Recall that
h = -b/2a
k = -(b^2 -4ac)/4a
2 = -b/2a
-b = 4a
b = -4a
Put b = -4a
k = -(b^2 -4ac)/4a
7= -(b^2 -4ac)/4a
7 = -((-4a)^2 -4ac)/4a
7 = -(16a^2 - 4ac)/4a
7 = (-16a^2 + 4ac)/4a
7 = -4a + c
c = 7 + 4a
The path of the jump also passes through (5,5)
y = ax^2 + bx + c
5 = a5^2 + b5 + c
5= 25a +5b + c
Put b = -4a in above
5= 25a +5(-4a) + c
5= 25a -20a+ c
5 = 5a + c
Put c = 7 + 4a
5 = 5a + 7 +4a
Collect like terms
5-7 = 5a + 4a
-2 = 9a
a = -2/9
Put a in
y = a(x^2 -4x +4) + 7
y = -2/9(x^2 -4x +4) + 7
y = (-2x^2 +8x -8)/9 +7
Multiple through by 9
9y = -2x^2 +8x -8 + 63
9y = -2x^2 +8x + 55
Dividing through by 9
y = -0.22x^2 +0.89x + 6.11
Therefore the equation of the jump is
y = -0.22x^2 +0.89x + 6.11.

The point (-7, 1) is in fact a solution for the inequality y < 0.5x + 9
Is the point (-7, 1) a solution to the inequality y < 0.5x + 9?
A point is a solution of a inequality only if it makes the truth value of the inequality true.
In this case, it would mean that the right side of the inequality is strictly larger than the left side.
So to check that, we just need to replace the values of the point on the inequality.
The values are x = -7 and y = 1, replacing that in the given inequality we will get:
1 < 0.5*(-7) + 9
1 < -3.5 + 9
1 < 5.5
This is true, 5.5 is larger than 1, then we conclude that the point (-7, 1) is in fact a solution for the inequality y < 0.5x + 9

b. Use the inverse to find the Celsius temperature that corresponds to 25⁰F .
The formula for converting from Celsius to Fahrenheit temperatures is F = 9/5 C + 32 then the inverse function is one-to-one.
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.
The formula for converting from Celsius to Fahrenheit temperatures is
F = 9/5 C + 32.
Let the Fahrenheit temperatures is F = 9/5 C + 32
Subtract 32 from both sides:
F - 32 = 9/5 C + 32 - 32
F − 32 = 9/5 C
Multiply both sides by 5:
5(F − 32) = 9C
Divide both sides by 9:
5/9 (F − 32) = C or C = 5/9 (F − 32)
For 27° F
⇒ C = 5/9 (27 - 32)

What is the Polynomial long division method?Polynomial long division is an algorithm in algebra for dividing a polynomial by another polynomial of the same or lower degree, which is a generalized version of the well-known arithmetic technique known as long division. It is simple to do by hand because it divides an otherwise complex division problem into smaller ones. It is sometimes faster to use a shorthand version called synthetic division, which requires less writing and fewer calculations. Polynomial short division (Blomqvist's method) is another abbreviated method.So, find the quotient of (x³+2 x²-x+6) / (x+3) using the Polynomial long division method:
(x³+2 x²-x+6) / (x+3) ⇒ R = 0 ⇒ quotient = x²-x+2As, (x²-x+2)(x+3) gives (x³+2 x²-x+6).Therefore, the quotient of (x³+2 x²-x+6) / (x+3) is (B) x²-x+2.
