We look at several examples of functions and see their domain. Sal writes the domain in set notion and shows how different functions can have different input values that cause the function to be undefined.

An instructional video explaining the concept of function inverses. A linear function is given and a diagram is drawn to show the mapping of some elements of the domain to the corresponding elements in the range. The inverse of the...

In this video students figure out the domain of a function.

The video resource shows worked examples of algebra concepts. Students watch a detailed problem on how to find the domain and range of a function. [3:34]
