1. The problem statement, all variables and given/known data Differentiate the functions using chain rule. 2(x3 −1)(3x2 +1)4 2. Relevant equations Chain Rule = f ' (g(x))g' (x) 3. The attempt at a solution I don't know how to do using chain rule, but product rule is easier So using product rule, = f ' (x) g(x) + f (x)g' (x) = (2)(x3-1)0(3x2)(3x2+1)4 + 2(x3-1)(4)(3x2+1)3(6x) = (2)(3x2)(3x2+1)4 + 8(x3-1)(3x2+1)3(6x) Can anyone show me how to do it, using chain rule?
