Designed for Algebra lesson on finding domain and range of graphs. Includes a review slide of finding domain and range from input/output tables and graphs with ordered pairs. Slowly progresses to graphs of lines and functions/non-functions. Provides opportunities for students to analyze what is different from the review examples to the new examples and discuss how they can write a domain and range that encompasses all values for x and y without writing a list. Includes a slide where students match a graph to a domain and range. Includes examples with finite endpoints as well as examples that approach infinity and negative infinity. Concludes with examples that ask students to draw graphs that fit a given domain and range.
