Question

I need help figuring this out!!

State whether each is a function or not and explain how you know.
a. (-4, -3), (-3, 2), (8, 2), (9, 6)

b. (5,6), (5, 1), (7, 9), (9, 8)

c. (1, 8), (-1, 1), (-2, 8), (-2, 6)

Answer 1

I wish I could help but I can’t this is too hard

Answer 2

heyo! Your answer for which one is a function is “a”. the best thing to remember about functions is that in your (x, y) you can never have the x value be the same in the same relation. for example if you have (3, 1) (3, 7) (6, 9) this can’t be a function because there are two of the same number (3) in the x placement, if we were to change one of those three’s for let’s say a 4 then it would be considered a function because there is not a repetition of the same number in the x value place, it’s also good to remember that you can have repeated numbers in the y place because it doesn’t matter as much.
i’m not entirely the best at explaining things but i hope this helps at lest a little bit :) have a wonderful rest of your day!
