Try another version of this question Given `y=f(u)` and `u=g(x)`, find `dy/dx=f'(g(x))g'(x)` for the following functions: `dy/dx=f'(g(x))g'(x)=`
Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
Recall the chain rule: for composite functions, `dy/dx = dy/du * du/dx`. In this problem, you're given `y` as a function of `u`, and `u` as a function of `x`. Your task is to find `dy/dx` by applying this rule. Remember to identify which function represents `dy/du` and which represents `du/dx` in the context of the given equations.
Be sure your variables match those in the question `12 x^2`
