Working with Polynomial Functions and Their Graphs Introduction Consider the function ᡘ䙦ᡶ䙧 = ᡶ⡰ − 6ᡶ + 5. The following information allows us to graph it. 1. By inspection, we see that this is a quadratic function (or 2nd degree polynomial function). Its graph is a parabola that opens upwards. 2. We also know that […]
