INVERSES

Find the inverse of  $f\left(x\right)=-4x-12$  

•  $f^{-1}\left(x\right)=4x-3$  

•  $f^{-1}\left(x\right)=\frac{x+12}{-4}$  

•  $f^{-1}\left(x\right)=\frac{1}{4}x+12$  

•  $f^{-1}\left(x\right)=-4x+12$  

Find the inverse of
 $f\left(x\right)=\frac{1}{4}x-7$  

•  $f^{-1}\left(x\right)=4\left(x+7\right)$
