Quadratic Equations and Inequalities
Quadratic Equations and Inequalities introduces students to the graphs of quadratics, teaches them to find the vertex, intercepts, discriminant, domain and range and interpret the graph in relation to these qualities. It also introduces students to the focus and directrix of parabolas, how to use a sign number line to find the shape of a graph, and other topics that might be found as exercises in homework. Topics include:
- Dilations of Quadratic Graphs
