Answer:

f^-1(x) = 1/5 x

Step-by-step explanation:

y = 5x

Exchange x and y to find the inverse

x = 5y

1/5x = y

The inverse is 1/5x

Answer:

\Large \boxed{f^{-1}(x)=\frac{x}{5} }

Step-by-step explanation:

f(x) = 5x

Replace f(x) with y.

y = 5x

Switch variables.

x = 5y

Divide both sides by 5.

\frac{x}{5} =y
