WebJan 17, 2024 · Use the inverse function theorem to find the derivative of g(x) = 3√x. Solution The function g(x) = 3√x is the inverse of the function f(x) = x3. Since g′ (x) = 1 f′ (g(x)), begin by finding f′ (x). Thus, f′ (x) = 3x3 and f′ (g(x)) = 3(3√x)2 = 3x2 / 3 Finally, g′ (x) = 1 3x2 / 3 = 1 3x − 2 / 3. Exercise 3.14.2
