Question

Find the inverse function F -1 (X) for the given function F (X)

Answer 1

Solution for question 5:

f(x) = 4x - 8

To find f^-1(x) write it as an equation:

y = 4x - 8

Then take x to left and y to right;

x = 4y - 8

Then solve for y;

y = (x + 8)/4 = x/4 + 2

Your y is the inverse of f(x) = 4x - 8

f^-1(x) = x/4 + 2
