Find the inverse of each function. Is the inverse a function?
f(x)=x³
To have an inverse function, a function must be one-to-one.
[tex]$$f^{-1[/tex](x) = x³ is the inverse of f(x) = x³
What is meant by inverse function?An inverse function, also known as an anti function, is a function that can be reversed into another function. Simply put, if any function " f " takes x to y, then its inverse will take y to x. The inverse function is denoted by [tex]$$f^{-1[/tex] or F-1 if the function is denoted by ' f ' or ' F '.
To find the inverse, interchange the variables and solve for y.
f−1(x)=3√x
Take the cube root of both sides of the equation to eliminate the exponent on the left side.
Replace y with [tex]$$f^{-1[/tex](x) then we get
[tex]$$f^{-1[/tex](x) = 3√x
[tex]$$f^{-1[/tex](x) = x³ is the inverse of f(x) = x³
The result of a mathematical operation, such as addition and subtraction, multiplication and division, is reversed. These are referred to as inverse operations. Typically, the inverse of a number is its reciprocal, or x - 1 = 1/x. A number and its reciprocal (inverse) product yield one.

Given f(x) = x² + 5x +6 and g(x) = x +2, find (f ◦ g) (x)
Answer:
x² + 9x + 20
Step-by-step explanation:
f(x) = x² + 5x + 6
g(x) = x + 2
Now, let us find (f o g)(x)
(f o g)(x) = f(g(x))
= f(x+2)
= (x + 2)² + 5(x +2) + 6
{Identity used: (a + b)² = a² + 2ab +b²}
= x² + 2*x*2 + 2² +5*x +5*2 + 6
=x² + 4x + 4 + 5x + 10 + 6
= x² + 4x + 5x + 4 + 10 + 6

Explain why (-8)¹/₂ !-(8)¹/₂ , but (-27)¹/₃ =-(27)¹/₃
[tex](-8)^\frac{1}{2} \neq -(8^\frac{1}{2})[/tex] because 8 is an odd power of 2 and [tex](-27)^\frac{1}{3} = -(27)^\frac{1}{3}[/tex] because 27 can be written with the power which a multiple of 3.
Consider [tex](-8)^\frac{1}{2}[/tex].
We know that 8 = 2³
So [tex](-8)^\frac{1}{2}[/tex] = [tex](-2^3)^\frac{1}{2}[/tex]
Also there is no real value for this expression. If 8 had an even power, then we would have got a real value. Because here 3 does not cancel with 2 completely.
Now for [tex]-(8^\frac{1}{2})[/tex] , this expression means the negative sign of the square root of 8. Even though 8 is not an perfect square, 8 has a real square root value. So this expression gives a real value. But the previous one does not.
Hence, [tex](-8)^\frac{1}{2} \neq -(8^\frac{1}{2})[/tex]
Consider [tex](-27)^\frac{1}{3}[/tex] = [tex](-3^3)^\frac{1}{3}[/tex] = -3, canceling out the 3 on the denominator with the power of (-3).
Also, [tex]-(27)^\frac{1}{3}[/tex] = [tex]-(3^3)^\frac{1}{3}[/tex] = -3 again.
Hence [tex](-27)^\frac{1}{3} = -(27)^\frac{1}{3}[/tex] .
This is because the power was a multiple of 3.

Multiple choice :

B) k=0
C) k<4
D) k<or = 0
E)k< or = 4
====================================================
Explanation:
Recall the discriminant formula is
d = b^2 - 4ac
which is the stuff found under the square root in the quadratic formula.
If d > 0, then the equation ax^2+bx+c = 0 will have two different real number roots.
So,
d > 0
b^2 - 4ac > 0
4^2 - 4(1)(k) > 0
16 - 4k > 0
16 > 4k
4k < 16
k < 16/4
k < 4 which points us to choice C
For example, if k = 0, then the equation x^2+4x+k = 0 becomes x^2+4x = 0. This has the two different roots of x = 0 and x = -4.

Equation formed: A= 1500e(.07)(4)Money in the account after 4 years: $1984.69Time until there is $5000 in the account: 30 yearsWhat is compounding?Compound interest is the contribution of interest to the principal sum of a loan or deposit or interest on interest plus interest. It is the result of reinvesting interest, or adding it to the loaned capital, rather than paying it out or requiring payment from the borrower, so that interest is earned on the principal sum plus previously accumulated interest in the following period. In finance and economics, compound interest is the norm.Compound interest differs from simple interest in that previously accrued interest is not added to the principal amount of the current period, resulting in no compounding.So,

Suppose that an ink cartridge is classified as being overfilled, medium filled, or underfilled with a probability of 0.40, 0.45, and 0.15, respectively. (a) what is the probability that a cartridge is classified as not underfilled? (b) what is the probability that a cartridge is either overfilled or underfilled?
The probability that a cartridge is classified as not underfilled is 0.85, while the probability that a cartridge is either overfilled or underfilled is 0.55.
Probability is defined as the likeliness of an event to occur, and ranges from 0 to 1 or can be expressed as percentage.
(a) If a cartridge is classified as not underfilled, it means that it is either medium filled or overfilled. Then the probability of that is the sum of the probabilities of the two.
P(underfilled) = P(overfilled) + P(medium filled)
P(underfilled) = 0.40 + 0.45
P(underfilled) = 0.85
(b) If a cartridge is either overfilled or underfilled, then its probability is the sum of their probabilities.
P(either overfilled or underfilled) = P(overfilled) + P(underfilled)
P(either overfilled or underfilled) = 0.40 + 0.15

Give one example of worded problem applying the polya's 4-steps in problem solving.

Step-by-step explanation:
Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving:
Step 1: Understand the problem.
Step 2: Devise a plan (translate).
Step 3: Carry out the plan (solve).
Step 4: Look back (check and interpret).
The example using the polya's 4-steps in problem solving is created along with the answer.
Let's apply Polya's 4-step problem-solving process to the following word problem:
Problem: Lily has twice as many apples as John. Together, they have 27 apples. How many apples does each person have?
Step 1 - Understand the Problem:
To solve this problem, we need to find the number of apples that Lily and John each have. We know that Lily has twice as many apples as John, and together, they have 27 apples. We need to determine the number of apples for each person.
Step 2 - Devise a Plan:
Let's use algebra to represent the number of apples. Let's say the number of apples John has is "x." Since Lily has twice as many apples as John, the number of apples she has is "2x." We know that together, they have 27 apples, so we can set up an equation:
x + 2x = 27
Step 3 - Execute the Plan:
Now, we'll solve the equation to find the value of "x."
3x = 27
x = 27 / 3
x = 9
So, John has 9 apples. Now, we can find the number of apples Lily has:
Lily's apples = 2 * 9 = 18
Step 4 - Review the Solution:
John has 9 apples, and Lily has 18 apples. Together, they have 9 + 18 = 27 apples, which matches the information given in the problem. Therefore, the solution is correct.
Answer:
John has 9 apples, and Lily has 18 apples.
