A)   21    B)  28      C) 14      D)  -4

Solution

Problem 7 :

A relation is graphed as shown.

Find all the values that are in the domain of this relation.

Solution

Answer Key

1)  Domain = {-3, 0, 1, 2}

2)  Domain = {-2, -1, 0, 1, 2}

3)  Range = {3, 4, 5, 8}

4)  Range = {3, 7, 9, 8}

5)  Range = {4, 0, -1, 7}

6)  y = 14

7)  Domain = {1, 3, 4, 6}
