02 A company sells widgets. The amount of profit, y, made by the company, is
related to the selling price of each widget, x, by the given equation. Using this
equation, find out what price the widgets should be sold for, to the nearest
cent, for the company to make the maximum profit.
y = -x2
= -X- + 1012 – 900

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
