## Homework Statement

f'(u) = 1 / (1 + u^3)

g(x) = f(x^2)

Find g'(x) and g'(2)

## Homework Equations

## The Attempt at a Solution

So the derivative of function f at u is: 1 / (1 + u^3)

That means g'(x) would be f'(x^2), but to find the general derivative of f at u is 1 / (1 + u^3) so can I just plug in x^2 for u so I get: 1 / (1 + x^6) ?
