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.
Lastly, students worked in groups of 3 and each were assigned specific tasks on 4 standard form equations. We will complete this group activity tomorrow.
