look at this mapping diagram: is this relation a function? yes no

Explanation:

Step1: Recall the definition of a function

A relation is a function if each element in the domain is mapped to exactly one element in the range.

Step2: Check each domain element

• The element (10) in the domain is mapped to (17) (one - to - one).
• The element (19) in the domain is mapped to (4) (one - to - one).
• The element (1) in the domain is mapped to (0) (one - to - one).
• The element (0) in the domain is mapped to (5) (one - to - one).

Since every element in the domain is mapped to exactly one element in the range.

Answer:

yes
