1. Consider the cubic function f ( x ) = ax^3 + bx^2 + cx + d where a ≠ 0. Show that f can have zero, one, or two critical numbers and give an example of each case.

2. Use Rolle's Theorem to prove that if f ′ ( x ) = 0 for all xin an interval ( a , b ), then f is constant on ( a , b ).

3.True or False. The product of two increasing functions is increasing. Clarify your answer.

4. Find the point on the graph of f ( x ) = 4 − x 2 that is closest to the point ( 0 , 1 ).

Given a general cubic function y = ax^3 + bx^2 + cx + d prove the following, a) That a cubic must change at a quadratic rate.          I believe this to be the derivative of the general cubic function, yielding dy/dx = 3ax^2 + 3bx + c b) That there are only 6 basic forms (shapes) for a cubic.         This question is where I get lost.
