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 should be able to:

  • Manipulate absolute value, quadratic, rational and radical expressions, equations, and/or inequalities.
  • Translate between graphical, numerical, verbal, and symbolic representations of functions.
  • Use variables to represent unknown quantities, create a function to model a situation and use algebra and/or technology to find and interpret a result.
  • Interpret properties of functions and relations, such as the meaning of ordered pairs, domain and range, maximum and minimum values, and intercepts. 

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.
