Students were given Cornell notes on graphing a quadratic in standard form. We completed the first 2 examples in class.
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.
