Ahhh, my bad forgot to mention. I found you the x and y values, but you need to do the pyrgahteka theorem to find the answer. 2^2 + 4^2 and square root the answer. Therefore, you come out with sq rt 20.

EDIT: My spelling is terrible and I can't remember the guy's name lol.

Thanks.
Do you also know how the extreme value theorem can be true if f(x) = x is continuous on every closed interval but has no minimum or maximum?

And, why do the Pythagorean theorem?
