What is the maximum value of

? I got 1, but the book says 2. Which one is right?

Actually I never watch Star Wars and not interested in it anyway, but I choose a Yoda card as my avatar in honor of our great friend bobbym who has passed away. May his adventurous soul rest in peace at heaven.

Neither. That function does not have a maximum.

If by maximum value you mean global maximum, then that polynomial clearly approaches infinity for large x, so it cannot have a maximum.

If you mean a local maximum, then it does have one (at x = -1).

Take a look at this:

If those ends keep going up that way, then he is right.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
