Question

look at this set of ordered pairs: (0, 0) (18, 3) (12, 11) (17, -6) (9, 0) (-10, 17) is this relation a function? yes no

Explanation:

Step1: Recall the definition of a function

A relation is a function if each input (x - value) has exactly one output (y - value). In other words, no two ordered pairs in the relation can have the same x - value with different y - values.

Step2: Check the x - values of the ordered pairs

The x - values of the given ordered pairs are: 0, 18, 12, 17, 9, - 10.
We can see that each x - value appears only once. That is, there is no x - value that is repeated with a different y - value.

Answer:

yes
