What is the inverse of the function f(x) = 4x + 8?
O h(x) = 1/4x - 2
O h(x) = 1/4x + 2
O h(x) = 1/2x - 2
O h(x) = 1/2x + 2

To find the inverse of a function, you swap the x and y values. So instead of y=4x+8, it becomes x=4y+8. Now you re-solve for y, and that’s your answer:

x=4y+8
x-8=4y
1/4x-2=y
So h(x)=1/4x-2, or the first option
