Beginning with linear functions, this lesson looks at functions of real world data defined by tables and graphs before moving into functions defined by equations.

The lesson begins with graphs of the Dow Jones Industrial Average and water levels of Lake Huron where points on the graph are interpreted.

A short lesson introducing the cube root and absolute value functions and their graphs.

The lesson begins with a comparison of data tables and graphs of two functions, one directly proportional (cost of gas) and the other exponential (population), before a definition for direct va

This lesson focuses on finding appropriate non linear functions to model real world phenomena.

To motivate the convention for negative and zero exponents, the lesson begins by observing the halving pattern found in continuously decreasing the exponent of a power of two by one.

Exponential notation for $$n$$th roots and radicals is introduced.

Using Kleiber's rule- which linked an animals metabolic rate to its mass- to motivate working with rational exponents, this lesson begins by linking work with $$n$$th roots from the last le

A calculator based introduction to systems of linear equations.
Using real world data, this lesson introduces linear regression using lines of best fit that may calculated by hand by selecting two pints that appear to fall on the line of best fit.
