Define the terms domain, range, function, vertical limit test, and linear function notation with your class. They can then, graph several equations applying the vertical line test to determine which are and which are not functions, write their own equations, identifying them as functions or not, while providing reasons to support their identification. The inverse of their functions is also discussed.
