Which function is the inverse of f(x) = –5x – 4?

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

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.
