    a function WILL NOT have 2 or more x values that are the same. They can have more then 1 y value the same, just not the x's. So look at your answer choices and see which one does not have repeating x terms...that will be your function.

    For instance, look at your first answer choice... your points are set up like (x,y).....and as you can see, all of the sets of numbers have an x value of 1.....repeating x values....NOT A FUNCTION.
