Answer:

The two functions are inverses.

Step-by-step explanation:

We are supposed to find whether the two functions are inverses.

[tex]f(x)=5x+4[/tex]

[tex]g(x)=\frac{x-4}{5}[/tex]

To find the inverse of f(x)

y = 5x+4

y-4=5x

[tex]\frac{y-4}{5}=x[/tex]

Replace x with y and y with x

So, [tex]\frac{x-4}{5}=y[/tex]

So, [tex]\frac{x-4}{5}=g(x)[/tex]

So,The two functions are inverses.
