Question

HELP PLEASE!! which of the following represents a function?

please explain too i don’t understand this.

Answer 1

The answer would be A because each x only has one y. Hope that makes sense!

Answer 2

A is a function because if draw a line right down the middle no other dots will intercept

Explanation:

A function is where one input has only one out put

As you can tell in the table(c) -3 is repeated that's what makes it not a function.same for B since there are more than one inputs it's not a function

Hope this helps!
