Find the inverse function! f ( x ) = 1 5 ( 10 x − 20 ) f\left(x\right)=\frac{1}{5}\left(10x-20\right) f ( x ) = 5 1 ( 1 0 x − 2 0 )

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

f − 1 ( x ) = 5 x + 2 f^{-1}\left(x\right)=5x+2 f − 1 ( x ) = 5 x + 2

f − 1 ( x ) = 1 2 x + 20 f^{-1}\left(x\right)=\frac{1}{2}x+20 f − 1 ( x ) = 2 1 x + 2 0

f − 1 ( x ) = − 1 5 ( 10 x + 20 ) f^{-1}\left(x\right)=-\frac{1}{5}\left(10x+20\right) f − 1 ( x ) = − 5 1 ( 1 0 x + 2 0 )
