5 0

Answer:

g(x)=\frac{x}{4}-3

Step-by-step 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=\frac{x}{4}-3

Let

g(x)=y

g(x)=\frac{x}{4}-3 ---> inverse of the function f(x)
