Question

Is this a function? (4,12) (4,15) (5,18) (5,21) (6,24)

Answer 1

Answer:

No this is not a function.

Step-by-step explanation:

This is not a function because some of the x-values repeat, which is not how a function works. For this to be a function, each x-value would have to be different. In this case, the 4 and 5 repeat in the x-values.
