4. Suppose a polynomial function has degree n. A. What do you think is the maximum number of xintercepts of this function? Explain. B. How many yintercepts do you think this function has? Explain. 5. Consider the function y = 2x3 + 4x2 x 1. A. What do you know about the graph just from looking at the function? B. Graphy = 2x3 +4x2 x 1 in the Gizmo to check your answer. Sketch the graph on the coordinate plane to the right. Draw and label the x- and yintercepts with their coordinates. 6. Consider the function y = x4 + x3 3x2 x + 2. A. What do you know about the graph just from looking at the function? B. Graphy=x4+x33x2x+2inthe Gizmo to check your answer. Sketch the graph on the coordinate plane to the right. Draw and label the x- and y-intercepts with their coordinates
