The inverse of this function is f(x) =
(3x + 15)/(4)


To find the inverse of any function, start by switching the x and f(x) term. Then solve for the new f(x). The result will be the inverse function. The step-by-step process is below for you.


f(x) =
(-15 + 4x)/(3) ----> Switch the x and f(x)


x =
(-15 + 4f(x))/(3) ----> Muliply both sides by 3


3x = -15 + 4f(x) ----> Add 15 to both sides


3x + 15 = 4f(x) ----> Divide both sides by 4.


f(x) =
(3x + 15)/(4)
