This compilation of domain and range worksheet pdfs provides 8th grade and high school students with ample practice in determining the domain or the set of possible input values (x) and range, the resultant or output values (y) using a variety of exercises with ordered pairs presented on graphs and in table format. Functions and relations worksheet answer key Key. The set of $x$-values defines the domain and the set of $y$-values defines the range.
