    Look for sets of points that have repeated x values to find the non-function. Example: { (5,7), (5,8), (10,19), (12,27) } The x coordinate x = 5 pops up more than once, so this relation isn't a function.

    so to find the answer for my question i would only have to find the x the repeats?

    yep it's (1,2),(3,2),(0,1),(3,5) since x = 3 shows up twice

    A function must produce exactly one output for any given input. With the input of 3, we ask ourselves "what is the true output? 2? or 5?". Since we don't know for sure we just say it's not a function
