Q #3. Ifetify the mapping diagram that represents the relation and determine whether the relation is function..{(- 3,-6),(-1,-6)

1 answer:
Every ordered pair has a second number of -6, so the mapping with -6 as the sole number on the right is the appropriate mapping. A mapping is only <em>not a function</em> if it maps a number to two or more different values (as shown in the top diagram of your attachment).
