Question

Is (0,5), (0,2), (4,-2) a function?​

Answer 1

No, (0,5), (0,2), (4,-2) is not a function.

Explanation:

A function means that each x-value has exactly one y-value.

In these given points, the x-value zero has two y-values: 5 and 2

Therefore (0,5), (0,2), (4,-2) is NOT a function.

Hope this helps!

Answer 2

Answer: No

Step-by-step explanation: The easiest way to tell whether or not a relation represents a function is to take a look at the x-coordinate of each ordered pair. If any of our ordered pairs have the same x-coordinate, then the relation is not a function.

Two of our ordered pairs have the same x-coordinate of 0 which means the relation cannot be a function.
