Answer:


g(x)=(x)/(4)-3

Explanation:

we have


f(x)=4x+12

Find the inverse

Let

y=f(x)


y=4x+12

Exchange the variables (x for y and y for x)


x=4y+12

Isolate he variable y

subtract 12 both sides


4y=x-12

divide by 4 both sides


y=(x)/(4)-3

Let

g(x)=y


g(x)=(x)/(4)-3 ---> inverse of the function f(x)
