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) ?
