What is the inverse of the function:

f (x) = 2/3x + 10

To find the inverse of a function, replace the variable "x" with "y". Also replace "f (x) " with just "x". Solve this equation for y.

f (x) = 2/3x+10

x=2/3y+10

Subtract 10 from both sides:

x-10=2/3y

Multiply both sides by "3/2":

(3/2) (x-10) = y

The inverse function is: f^-1 (x) = 3/2x - 15
