Graphing a Horizontal Parabola Using Properties
To graph a horizontal parabola of the form or using its properties, follow a six-step procedure:
Step 1. Determine whether the parabola opens to the left or to the right. Step 2. Find the axis of symmetry. Step 3. Find the vertex. Step 4. Find the -intercept. Find the point symmetric to the -intercept across the axis of symmetry. Step 5. Find the -intercepts. Step 6. Graph the parabola.
