Example 6: Graph y = 2x^2 - 8x

Graph• yFind =the 2x2vertex and the axis of symmetry. Sketch these in.
8x• Find the x-intercept by plugging in 0 for y.
• Find the y-intercept by plugging in 0 for x.
• Reflect your points across the axis of symmetry and connect your dots with a smooth
U-shaped (not V-shaped) curve.
