Step-by-step 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

$$\frac{x+4}{-5} = y$$ or we can write that

-the inverse of f(x) = -5x -4 is $$f(x)^{-1}$$

$$f(x)^{-1} = \frac{-(x+4)}{5} = \frac{-x-4}{5}$$
