If (fx) = 5x, what is f^-1 (x)

x/5

Step-by-step explanation:

To get the inverse function you need to leave the x alone and then switch variables (f (x) = y)

f (x) = 5x

y = 5x

y/5 = x

Now that x is alone you switch the x for y and the y for x and you get:

x/5 = y

And this new y is the inverse function of f (x) (f^-1 (x))

f^-1 (x) = x/5
