Determine whether or not the inverse of the function f(x) is a function

• Function

• Not a Function

What is the inverse function of

 $f\left(x\right)=x^{2\ }+4x+4$  ?

• Does not have an inverse

•  $f^{-1}\left(x\right)=2x$  

•  $f^{-1}\left(x\right)=-2+\sqrt{x}$  

•  $f^{-1}\left(x\right)=x+2$  

What is the inverse of

 $f\left(x\right)=2x-4$  

• Does not have an inverse

•  $f^{-1\ }\left(x\right)=x+2$  

•  $f^{-1\ }\left(x\right)=\frac{x+4}{2}$  

•  $f^{-1}\left(x\right)=2x+8$
