{GQE St Fm Eq with Graph.PNG} Key Information
As you can see from the graph, the y-intercept is (0, 6). If we look at the graph in standard form the y-intercept is the "c" value! The y-intercept is the key information that we can obtain directly from the equation. So without doing much work we can find the y-intercept.
...
find the axis of symmetry,y-intercept, we will
...
then graph anotheran additional point.Let's
Example 1: Graph the following quadratic function: y = x2 - 6x + 4
1 - Key informationRecall the y-intercept is the c value so the y-intercept is (0, 4).
