Chp. 5.2 ­ Solving Quadratic Eqs. by Graphing Algebra II 2 February 13, 2013 Notes: Arielle works in the marketing department of a major retailer. Her job is to set prices for new products sold in the stores. Arielle determined that for a certain product, the function f(p) = ­6p 2 + 192 p ­ 1440 tells the profit f(p) made at price p. Arielle can determine the price range by finding the prices for which the profit is equal to \$0. This can be done by finding the solution of the related quadratic equation, which is zero. Graph the quadratic equation and state the range the profit is in. * Quadratic Equation = Quadratic functions that are set = to a value. * Standard Form ­­> 0 = ax 2 +bx + c * Roots = Solutions to a quadratic equation.
