Hi,

Would anyone be able to tell me how I'd go about solving a problem like this. Are you taking the derivative of the entire problem or just the one in the parenthesis (f(4x^3))? The inclusion of (f) is also throwing me off, not sure if that's supposed to be part of the solution. Is the answer supposed be something like = 12x^2(f'(4x^3))? Any help on this would be greatly appreciated. Thanks! Ana

Here's the problem . . .

d/dx(f(4x^3)) = 6x^5

Calculate f'(x) = ?
