Question

algebra 1 〉 m.4 identify functions vll
look at this set of ordered pairs:
(-13, 3)
(2, 17)
(4, 0)
(20, 17)
(-7, 0)
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: - 13, 2, 4, 20, - 7.
Check if any x - value is repeated. Here, all x - values (-13, 2, 4, 20, -7) are unique. So each input has one output.

Answer:

yes
