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

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

what level of math? also i don't need to be paid if i can you.
