Homework Statement
If d/dx (f(2x^4)) = 8x^5
Calculate f'(x)
Homework Equations
The Attempt at a Solution
Well , we have been only doing derivatives for 2-3 class and its new for me.
From what I understand in this question is.
You have a function f(x) = something
The derivative of this function when you plug in 2x^4 gives you 8x^5
With that i suppose I should be able to find the equation of f(x) and then give f'(x) but I really don't know how to actually do this.
