Find the inverse function of f(x)=4x+12
F(x)=4x+2F(x)=4x+2F(x)=4x+2
We Isolate X from the expression
Subtract 2 from both sides
F(x)−2=4x+2−2F(x)−2=4xF(x)-2=4x+2-2\\ F(x)-2=4xF(x)−2=4x+2−2F(x)−2=4x
Divide both sides by 4
X=F(X)−24=XX=\frac{F(X)-2}{4}=XX=4F(X)−2=X
Replace X by G(X) and F (X) with x
G(X)=X−24G(X)=\frac{X-2}{4}G(X)=4X−2
The inverse of the function is
