Videos, worksheets, games and acivities to help Algebra 1 students learn how to find the domain and range of functions.

Domain and Range
How to find the domain and range.
An important part of understanding functions is understanding their domain and range. Domain and range are all the possible x-values and y-values of the function, and can often be described easily by looking at a graph. In order to grasp domain and range, students must understand how to determine if a relation is a function and interpreting graphs.

This video provides two examples of how to determine the domain and range of a function given as a graph.
