What is the inverse of the function below? f (x) = 3x A. B. C. D.

Inverse function:

Step-by-step explanation:

The inverse of a functon is the function such that .

In this problem, the function that we have to reverse is

In order to reverse the function, we do it in this way:

1) First, we isolate x and we write it as a function of y. Therefore:

2) Then, we exchange the names of the variables, so:

Therefore, the inverse function is

-5k - 10

Step-by-step explanation:

Given:

-k + 2 ( -2k - 5)

Open parenthesis

-k - 4k - 10

Simplify like terms

-5k - 10

Answer is

(Choice B) B -5k-10−5k−10minus, 5, k, minus, 10

-k + 2 ( -2k - 5) is equivalent to -5k - 10
