Question

Which represents the inverse of the function f(x) = 4x?

O h(x) = X + 4
• h(x) =X- 4
O h(x) = =x
O h(x) = ÷x


PLEASEE HELP

Answer 1

f^(-1) = x/4

Explanation:

1. Starting with f(x) = 4x, replace 'f(x)' with y: y = 4x

2. Interchange x and y: x = 4y

3. Solve for y: y = x/4

4. Replace this y with 'f^(-1) = ": f^(-1) = x/4
