Khan Academy: Algebra: Domain and Range of a Function Given a Formula

This comprehensive unit on linear and exponential functions provides numerous clearly-written worksheets. Topics include graphing linear equations, solving systems of equations algebraically and by graphing, identifying the domain and...

The short example shown in this video starts with a given set of numbers in the domain and the range that represents a function. One needs to map the points on a coordinate plane.

Introduce zeros of a function and their relationship to the graph of the function. an informative video uses the definition of a zero to help identify them on a graph and provides several examples of finding the zeros of a...

If your students can't remember the difference between domain and range, then here's a video for you. Scholars learn to identify the domain and range of nine basic function types: constant, linear, absolute value, quadratic, cubic,...

After defining a simple function from a word problem, a short video shows how to find its domain and range. The instruction reinforces the definitions of domain and range with a concrete example.

A straightforward explanation of domain and range. The domain of a set of coordinates are the x-values, and then range are the y-values of the set.

A straightforward explanation of domain and range. The domain of a set of coordinates are the X-values, and then range are the Y-values of the set.
