Question

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

Answer 1

Explanation:

Find the inverse function of f(x) = -5x -4 or y = -5x -4

- change x with y and y with x

y = -5x -4 ,

x = -5y -4

- find y

x = -5y -4 , add 4 to both sides

x+4 = -5y, divide both sides by -5

`(x+4)/(-5) = y` or we can write that

-the inverse of f(x) = -5x -4 is
`f(x)^(-1)`

`f(x)^(-1) = (-(x+4))/(5) = (-x-4)/(5)`
