Answer

Explanation:

Step1: Check if it's a function

A relation is a function if each input (x - value) has exactly one output (y - value). In the set ({(0,9),(1,2),(9,2),(3,7),(4,6)}), the x - values are (0,1,9,3,4). Each x - value appears only once, so each input has exactly one output. So this relation is a function.

Step2: Check if it's one - to - one

A function is one - to - one if each output (y - value) corresponds to exactly one input (x - value). The y - value (2) corresponds to two different x - values ((x = 1) and (x=9)). So the function is not one - to - one.

Answer:

B. A function, not one - to - one
