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

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

Step-by-step explanation:

f(x) = -5x - 4        Substitute f(x) with y

y = -5x - 4         Switch the x and y variables

x = -5y - 4          Solve it down

x + 4 = -5y

y = (x + 4)/ -5

f^-1(x) = (x + 4) / -5          < This is the answer

(x, y)→(x − 8, y − 7)
