Hello!

Let's solve this question with the information given to us in the question.

We were given the function, f(x) = -5x - 4, or also known as y = -5x - 4

With the function we need to find the inverse of it.

We can simply flip the "x" and "y" variables in the function and solve.

Solve:

y = -5x - 4

Flip the "x" and "y" variables.

x = -5y - 4

Now, solve for "y".

x = -5y - 4

Add 4 to both sides of the equation.

x + 4 = -5y

Divide everything by -5 to get "y" by itself.

-1/5x - 4/5 = y

Therefore, the inverse of the function would be
-(1)/(5)x -(4)/(5)

Answer:

Your answer would be A).
-(1)/(5)x -(4)/(5)
