Answer:
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
[tex]\frac{x+4}{-5} = y[/tex] or we can write that
-the inverse of f(x) = -5x -4 is [tex]f(x)^{-1}[/tex]
[tex]f(x)^{-1} = \frac{-(x+4)}{5} = \frac{-x-4}{5}[/tex]
