Quadratic Functions
This module begins by showing how the world is full of parabolas—at a baseball game, supporting a suspension bridge, at a water fountain. The module defines a parabola as a conic section, and allows students to create different parabolas that all share the same geometric properties. The general form of a quadratic function y = ax2 +bx + c is also presented, followed by an interactive activity where students can change a, b, and c to see how these changes affect the graph.
Polynomial Functions
This module begins by showing how to make a box out of cardboard that has maximum. It presents a discussion of polynomial functions and classifies them according to the number of terms (type) and according to its degree (order). The definition of a cubic polynomial function and the general form of the equation
Linear Functions
This module opens with a discussion of practical problems that can be solved using linear functions—calculating a runner’s desired pace, and figuring out the best cell phone plan. Along the way, the slope of a line and linear functions are defined. The module presents the slope-intercept form, the point-slope form, and the general form for the equation of a line, along with examples and interactive activities for finding each. Then, it moves to a description of a method for solving linear inequalities along with examples and interactive activities. Students are prompted to find the equation of a line given a graph and to graph a line given an equation.
Fundamental Topics in Algebra Series
In this series, students learn about linear functions, quadratic functions, polynomial functions, and rational functions. The series includes real-life examples that help students understand the role mathematics plays in making everyday decisions
