Look back at the graph...
(Relative extrema (maxs & mins) are sometimes called local extrema.)
Other than just pointing these things out on the graph, we have a very specific way to write them out.
Officially, for this graph, we'd say:
f has a relative max of 2 at x = -3.
f has a relative max of 1 at x = 2.
So, saying that the max is (-3, 2) would be unclear and not really correct.
