Reference Guide: Discriminant and X-Intercepts
You are developing a technical reference guide for junior data analysts working with quadratic modeling. State the three rules that define the relationship between the value of the discriminant () and the number of x-intercepts (points where the model reaches zero) on the graph of a parabola. Specifically, identify how many x-intercepts occur for a positive, negative, and zero discriminant.
