Exercise 6 Page 278

We want to draw the graph of the given quadratic function. To do so, we will rewrite it in vertex form, where and are either positive or negative numbers.
To draw the graph, we will follow four steps.
  1. Identify the constants and
  2. Plot the vertex and draw the axis of symmetry
  3. Plot any point on the curve and its reflection across the axis of symmetry.
  4. Sketch the curve
