It is important to find the vertex using the formula x = -b/(2a) and then subbing in to get the corresponding y-value. The "c" is the y-intercept and we used the axis of symmetry to help generate more points.

We also asked if there were any questions with the WS Test Prep 4.1/4.2 from yesterday. This should be completed and will be collected tomorrow.
