f f (x) = 5 x minus 25 and g (x) = one-fifth x + 5, which expression could be used to verify g(x) is the inverse of f(x)?

We study if the composition of both functions equals the identity ("x"), that is if

Step-by-step explanation:

The composition of the two functions should render 'x" if one is the inverse of the other. That is, we need to find what   renders. Notice as well that the same verification could be done with examining  .

Let's work with :

So we see that the composition of both functions indeed render "x", and that way we have verified that one is the the inverse of the other.

B. One-fifth (5 x minus 25) + 5

Step-by-step explanation:

Just got it right on the test.

step-by-step explanation:

the first option is the answer.
