www.scasd.orgI can use the discriminant to determine the number and type of solutions/zeros. Modeling with Quadratic Functions 1. I can identify a function as quadratic given a table, equation, or graph. 2. I can determine the appropriate domain and range of a quadratic equation or event. 3.

We find another solution by the technique of variation of parameters. We try y uerx, where u is a new unknown function. Now, the differential equation is

In these lec-ture notes, we attempt to demystify some of the fancier properties of multivariate Gaussians that were introduced in the recent factor analysis lecture.
