(4,-2),(6,3),(4,2),(5,4)
Is the set of ordered pairs shown above a function?

No.
In a function, every x has only 1 y. In other words, if you put x into the function, you could only get 1 answer. In here you see that if you put a 4 in, you could get either -2 or 2, therefore it is not a function.

If the same x value can produce different y values, it's not a function, otherwise it is. So you look at the x values and see if any are repeated, and for each pair of repeated values, look at the y values to see if they're different. If they are different, it's not a function. (And remember that an ordered pair is given in the form (x,y)!)

no it's not.. because the set contains two points that have the same x-coordinate.
in a function, the rule is that to every x in the domain, there should correspond *exactly one* y-value.

No.
Function = X cannot repeat
(The first number of each ordered pair.)

anytime you have a repeating x value, the coordinates do not create a funtion
ANS : NO
