Gizmo Warm-up In the Graphs of Polynomial Functions Gizmo TM, you will explore the intercepts and behavior of polynomial functions up to the fourth degree. 2 On the CONTROLS tab, set a and b to 0.0. You can change the values of a, b, c, , and f by dragging the sliders, or by clicking in the text field, typing in a value, and hitting Enter. 1. Drag the sliders to vary the values of c, d, and f to explore a variety of quadratic functions or second-degree functions. (The degree of a polynomial is the greatest power of x.) A. Turn on Show intercepts. What is the maximum and minimum number of x-intercepts a quadratic function can have? Maximum: Minimum: B. How many y-intercepts does a quadratic function have? 2. Now just vary c, the coefficient of x2. How does the sign of c affect the graph
