22. The path of a roller coaster over a particular length of track can be represented by a quadratic function f, where f(x) represents the vertical displacement above or below a support bar (in meters), and x represents the horizontal displacement to the left or right of a flagpole (in meters). The roller coaster dips below the support bar for values of x between and 1. Which function could represent f ? 23. A company produces swimming pools. Its daily cost can be modeled with the function P(x)=20x2 – 240x, where x is the number of swimming pools produced. If the company makes at least 1 pool a day, how many pools need to be produced for the company to break even?
