Given that f(u) = u and g(x) = 3x + 5. Consider the following computations using the chain rule to find the derivative of the composition. f(g(x)) = (3x + 5)4 f'(u) = 4u f' (8(x)) = 4(3x +5) 8 (x) = 3 (f . g)' = 12(3x + 5) Therefore, (f . g)' = 12(3x + 5). Which of the given computations are incorrect? (Select all that apply.) Of(g(x)) is incorrect. Of'(u) is incorrect. O f' (g(x)) is incorrect. g' (x) is incorrect. (f . g)' is incorrect. Use the chain rule to find (f . g)
