    you draw lines that are pretty much straight up and done the graph; if they hit in more than one spot; its not a function

    a function is defined as one y for every x; so if a vertical line hits 2 ys; it fails tha function definition

    if I tell you that I am 12 years old and that I am 65 years old; can both be true?

    WAIT. i get it. you have to graph the function table, then draw a line through it, and if it goes through more than one, its not a function?
