The focus of this course is on function relationships and problem solving in real situations. Students use symbols to represent relationships between quantities, study the meaning, properties and attributes of functions, use linear and quadratic functions and equations to represent and model problem situations, and use a variety of methods to solve linear and quadratic equations as well as linear inequalities. They translate among and use algebraic, tabular, and graphical methods to represent linear and quadratic functions and to solve systems of equations. They investigate, describe, and predict the effects of changes on the graphs of linear and quadratic functions. They relate direct variation to linear functions and solve problems involving proportional change. **PRE AP/IB - Upon successful completion, the student will receive one elective credit counting toward high school graduation. Semester grades earned are included in the high school GPA as weighted grade points.
