The value of b^2-4ac gives us some immediate information about how the graph of our Quadratic Function will look. This video discusses the three scenarios one will run into when trying to graph a Quadratic Function.

Some images made using Geogebra.

Informational stops:
0:38 - Possible values of the discriminant.
1:41 - Positive discriminant tells us we have two x-intercepts.
2:29 - Discriminant equal to zero tells us we have one x-intercept.
3:32 - Negative discriminant tells us we have no x-intercepts.
4:20 - Summary of the three potential situations.
