Step 3: Find the relative maximum and/or the relative minimum between each x intercept. Halfway between the first two points: -4 Evaluate the polynomial at this point: 1. Halfway between the second two points: -2 Evaluate the polynomial at this point: -1. Step 4: Sketch a rough graph. Use the line segments to approximate a curve. Drag the points as needed and label them. Label the scale of the y axis. (x, y) x, y x, y (x, y) (x, y)
