The tutorial is wrong. With a guess value of 30 the answer should be 32.19.

I am not sure what your question is?

In case you are confused because maximize did not return x=0, the absolute maximum: "maximize" is a numerical algorithm which will always return a LOCAL maximum within a certain numerical tolerance. The value you end up with depends on the guess value.

If you search for absolute maxima and minima you may be interested in Minimizing a Function using Simulated Annealing

BTW, you don't need to use a solve block if you use maximize without any constraints:
