(a) Suppose that f is a polynomial of degree 3 or more. Explain, in your own words, how you would

use real zeros of f to determine the open intervals over which f(x) > 0 or f(x) < 0. Be brief

and precise. In particular, you need to tell how and where the sign of f changes.

(d) Rewrite the expression (cos x)2x in terms of natural base e.

4. Let f(x) = x2 + 5. Find lim_h-0 f(3+h) - f(3)/h
