There are a few key features to look for when matching a quadratic function with its graph: whether "a," the leading coefficient, is positive or negative to open up or down; the y intercept that is found when x = 0; and the focus of this lesson, which is how many xintercepts you can expect. The discriminant, which is the value of "b squared minus 4ac," tells us if we can expect zero, one, or two xintercepts.
