Question

Determine whether or not each relation is a function. Explain.

Answer 1

6. Yes, that relation is a function because only the y variables are the same, the x variables are completely different.

7. No, that relation is NOT a function because there are 2 x variables that equal different y variables (i know the y variables are different, but the x variables must be different for it to be a function, just remember that and you'll do fine! :3).
