This one max min is always the same technique.

There is another method using calculus (later topic), but it’s not very efficient.

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.
