Question

algebra 1 〉 m.4 identify functions vll
look at this mapping diagram:
domain range
-14 2
12 2
0 2
8 13
-11 7
19 7
is this relation a function?
yes no

Explanation:

Step1: Recall function definition

A relation is a function if each input (element in domain) has exactly one output (element in range).

Step2: Check domain elements

Check each domain value: -14, 12, 0, 8, -11, 19. Each has only one arrow (one output). Even if range values are reused, the key is domain elements have unique outputs.

Answer:

yes
