Question

look at this set of ordered pairs: (7, 20) (-16, -14) (10, 5) (5, 10) is this relation a function? yes no

Explanation:

Step1: Recall the definition of a function

A relation is a function if every input (x - value) has exactly one output (y - value), i.e., no two ordered pairs 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 7, - 16, 10, and 5. Each of these x - values appears only once. So, for each x - value, there is exactly one corresponding y - value.

Answer:

Yes
