Suppose that an equation is given p = −2x2 + 256x − 1000, where x represents the number of items sold at an auction and p is the profit made by the business that ran the auction. How many items sold would make this profit a maximum?Solve this by graphing the expression in your graphing utility and finding the maximum using 2nd CALC maximum or, for the TI-89, F5 for the math menu and 4:Maximum. To obtain a good window for the curve, set x [0, 200]
and
y [0, 10000].
