Answer 2

The function g(x) can be expressed as the inverse of f(x) as;

g(x) = ¼x - 3

Inverse Functions

Complete question is;

If g(x) is the inverse of f(x) and f(x) = 4x + 12 what is g(x)?

• Now, for us to find the inverse of a function, we need to make the output the subject of the formula first and then switch the input and new output values.

Thus;

f(x) = 4x + 12

Thus;

(f(x) - 12)/4 = x

x = ¼f(x) - 3

Thus, switching as said above, we now have;

g(x) = ¼x - 3
