Find the domain and the range of the relation. (Hint: Remember that you cannot divide by 0 or take the square root of a negative number.) {(2, 2), (4, 4), (7, 7)} STEP 1: Collect all the numbers that come first in each ordered pair of the relation. (Enter your answer in roster notation.) domain: STEP 2: Collect all the numbers that come second in each ordered pair of the relation. (Enter your answer in roster notation.) range:

Use complete sentences to describe a relationship between two sets that you can describe mathematically. For example, if you make a habit of eating 10 carrot sticks a day you could mathematically describe the relationship between the number of days in the month and the number of carrot sticks you eat in that month.

For each relation below, determine whether it is a function and state its domain and range. a) {(-5, 2), (-3, 3), (-1, 4), (1, 5)} b) c) Function? (circle) Yes/No Domain: Range: 10 -20 x -5 5 10 Function? (circle) Yes/No Function? (circle) Yes/No Domain: Domain: Range: Range:
