Even after this we must still find out which value of x corresponds to min y and which value of x corresponds to max y.

So, this method is inefficient.

Currently I am outside, but I am able to do some writing, so I can still answer questions (though at a slower rate).

I will return at 12 am and be available from 12:30 am to 2 am.
