iNVERSE fUNCTION

FInd the inverse of the function.
 $f\left(x\right)=\frac{3x-15}{2}$  

•  $f^{-1}\left(x\right)=-x-5$  

•  $f^{-1}\left(x\right)=3x+5$  

•  $f^{-1}\left(x\right)=\frac{15+2x}{3}$  

•  $f^{-1}\left(x\right)=\frac{2}{3}x-\frac{19}{3}$  

Find the inverse of the function.
 $f\left(n\right)=-4-\frac{2}{5}n$  

•  $f^{-1}\left(n\right)=\frac{-6-5n}{2}$  

•  $f^{-1}\left(n\right)=3n-4$  

•  $f^{-1}\left(n\right)=-\frac{5}{2}n-10$  

•  $f^{-1}\left(n\right)=\frac{-2n-4}{5}$  

 $f\left(n\right)=-n^3+2$  
Find the inverse of the function. 

•  $f^{-1}\left(n\right)=\left(n+1\right)^5$  

•  $f^{-1}\left(n\right)=^3\sqrt{-n+2}$  

•  $f^{-1}\left(n\right)=2n^5$  

•  $f^{-1}\left(n\right)=\left(n+3\right)^5$
