Question

Help with derivatives please

Answer 1

For b), use the chain rule.
\[\large [f(g(x))]' = g'(x) *f'(g(x))\]

Answer 2

For c) use the chain rule to find first derivative, and then product rule to find second derivative.\[\large [(f(x))^2]' = 2 f(x)*f'(x)\]Now just use the product rule to find the second derivative.

Answer 3

For d) use the quotient rule.
