## Customize your Student Experience

Edfinity is a full-featured homework system. Use this problem series as-is, or mix-and-match with other series or your own problems as desired. Edfinity gives you complete control over the every aspect of students' online assessment experience.

## Intended Outcomes

Upon completion of the course students will be able to:

- Convert between different polynomial forms using operations and factoring.
- Represent quadratic functions in various forms: symbolic, graphical, numerical, and verbal.
- Use variables to represent unknown quantities and create models using linear equations, quadratic equations, and systems of equations.
- Make predictions and interpret the results for models using linear equations, quadratic equations, and systems of equations.
- Recognize and differentiate between linear and quadratic patterns in ordered paired data, graphs, and equations.
- Interpret properties such as ordered pairs, and maximum and minimum values in a quadratic relationship.

## Powered by WeBWorK

This problem series includes WeBWorK-enhanced problems. WeBWorK problems are highly sophisticated, supporting the representation and manipulation of mathematical objects such as vectors, points, matrices, intervals, and complex numbers, with customizable answer checkers. Students are encouraged to make multiple attempts until they succeed, and given immediate feedback on correctness.

Edfinity provides full access to the WeBWorK Open Public Library (OPL), a collection of over 20,000 rich, interactive problems across a wide range of math and science subjects, including college algebra, discrete mathematics, probability and statistics, single and multivariable calculus, differential equations, linear algebra and complex analysis.
