Find the profit function, which is a quadratic function and satisfies ALL the following conditions: (a) the company breaks even when and units are produced, (b) the maximum revenue is
(correct).
None of above.
Find a profit function satisfies ALL the following conditions, where denotes number of units are produced and is a polynomial function: (a) the company breaks even at and units (b) the profit function changes signs (from to or vise versa) at but does not change sign at and (c) the company is not profitable when units are produced.

True or False:
Any odd degree polynomail has at least one x-intercept.
Any even degree polynomail has at least one x-intercept.
The function has no in the interval of [0, 1].
For a degree four polynomial, the number will affect the graph of in horizontal direction.
