Day 20: Domain and Range  Bellringer Evaluate and graph y = |x|-2 Fun question: What's your favorite book and why?  Learning Goal TSWBAT understand and determine the domain and range of functions, and write them in interval notation.  What do you know? What do you know about domain and range?  Definitions Domain: The set of all possible input values (x-values) of a function. Range: The set of all possible output values (y-values) of a function.  Practice with Ordered Pairs Determine the Domain and Range: {(1, 2), (3, 4), (5, 6)} {(-1, 0), (2, -3), (4, 5)}  Try These Ordered Pairs Determine the Domain and Range: {(0, 1), (2, 3), (4, 5)} {(-2, -1), (0, 0), (3, 4)}  Interval Notation Writing in Interval Notation: - Use parentheses () for values that are not included (open intervals). - Use brackets [] for values that are included (closed intervals).  Closing Question What are the rules for choosing either () or [] for your interval notation, in your own words?
