SOLVING QUADRATIC EQUATIONS

GRAPHING QUADRATIC EQUATIONS

Step 1: Find the x-coordinate of the vertex. The x-coordinate of the vertex is called the axis of symmetry. You can find it using: x = -b/2a.

Step 2: Create a table of values including a few points above and below the axis of symmetry.

Step 3: Plot the points and graph the equation.
