Question

part 3: is it a function?
decide if the relations below are functions. circle yes or no. (1 pt each)
yes no yes no
yes no

Explanation:

Step1: Recall the definition of a function

A function is a relation where each input (element in the first set) has exactly one output (element in the second set).

Step2: Analyze the first relation

In the first relation, each element in the left - hand set (0, 2, 3, 6, 9) is mapped to exactly one element in the right - hand set. For example, 0 is mapped to 0, 2 is mapped to 0, 3 is mapped to 6, 6 is mapped to 6, 9 is mapped to 6.

Step3: Analyze the second relation

In the second relation, the element 1 in the left - hand set is mapped to 0, the element 3 is mapped to 2, the element 6 is mapped to 5, and the element 9 is mapped to 8. Each input has exactly one output.

Answer:

For the first relation: YES. For the second relation: YES.
