    if x values are repeating then relation is not a function if there are same x values more than one time then relation is NOT a function (x,y) first number is x-coordnate

    x values are not repeating so sets of ordered pairs represents function or not ?

    just look at the x-coordinate if x values repeating then relation is not a function if they don't repeat then relation is a function
