Question

What is the inverse of the function f (x)=19/x^3

Answer 1

Answer: f^-1(x) = 19^3/x

Explanation:

Given that : f(x) = y = 19/x^3

x^3 = 19/y

y = (19)^3/x = f^-1(x)

Answer 2

Below

Explanation:

y = 19/x^3 <===== solve for 'x'

x = cube rt (19/y) < ====now switch the x and y's

y = cube rt ( 19/x)
