## Homework Statement

Supposed "f" is a differentiable function. Write the expression for the derivative of the following function.

a) h(x) = -4x^3 * f(x)

b) h(x) = 2/[tex]\sqrt{x}[/tex]* f(x)

## Homework Equations

N/a

## The Attempt at a Solution

Would the answers just be (using the product rule)

a) h'(x) = -4x^3 * f '(x) + f(x) * -12x^2

and

b) h'(x) = 2/[tex]\sqrt{x}[/tex] * f '(x) + f(x) * -x^-2

Sort of seems to simple... Thanks again
