Which of the following represents a function? explain too i don’t understand this.

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

Step-by-step 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
