I just want to confirm if the local maximums in the graph are indeed f(-3)=4 and f(2)=3 because in the graph used in page 100 it is stated there that the graph’s local maximum is (-2,4.5). Why are there only 1 local maximum in the example while there are two local maximums in the graph used in exercises 42-57?
Lastly, I don’t quite understand why there is no local minimum in the graph of example 1.6.4. Can you please explain it a bit differently? Thanks.
