Prerequisites – passed Math 1. This course is the second in the sequence of classes in an integrated and investigative mathematics program. The focus is on quadratic expressions, equations, and functions; comparing their characteristics and behavior to those of linear and exponential relationships from Math 1. The need for extending the set of rational numbers arises and real and complex numbers are introduced so that all quadratic equations can be solved. The link between probability and data is explored through conditional probability and counting methods, including their use in making and evaluating decisions. The study of similarity leads to an understanding of right triangle trigonometry and connects to quadratics through Pythagorean relationships. Conic sections, especially circles, and their quadratic algebraic representations will round out the course. This course will meet the subject area – C requirement for the UC/CSU approved course list. This course meets the mathematics requirement for graduation.
