Ch. 4.3
1.) Find f'(x) for f(x) = $\frac{x^2\sqrt{x}+x\sqrt{x^3}-(x\sqrt{2})}{(x^{2/3})^2}$
2.) Find g'(x) for g(x) = $\frac{ax+b}{cx+d}$ where a, b, c, d are constants.
3.) Find f''(x) for f(x) = $(x^2 - \sqrt{x})3^x$
4.) Say that Æ’ and h are functions and that f(3) = 2, f'(3)=-2, h(3) = 1 and h'(3) = 4. Find p'(3) where p(x) = $\frac{f(x)}{x^2h(x)}$
