f^(-1)(x) = \frac{-1}{5} (x+4)
Step-by-step explanation:
Given is a function
To find its inverse.
We must check whether f is one to one or onto first
If -5x1-4 = -5x2-4 we get x1=x2
Hence f is one to one
Also for every f(x) we can find a x so f is onto.
So inverse exists
Let
Replace x by f inverse and y by x
