Question

algebra 1 > m.4 identify functions vll look at this set of ordered pairs: (12, 4) (18, 1) (6, 4) (10, 2) (-11, 19) is this relation a function? yes no

Explanation:

Step1: Recall function definition

A relation is a function if each input (x - value) has exactly one output (y - value).

Step2: Check x - values

List the x - values from the ordered pairs: 12, 18, 6, 10, - 11.
Check if any x - value is repeated. Here, all x - values (12, 18, 6, 10, - 11) are unique. So each input has exactly one output.

Answer:

yes
