Answer:
-2
2
Step-by-step explanation:
just use common sense. what does "local maximum" mean ?
it means a point, where the curve in the nearest neighborhood does not have a higher value. where the curve comes from smaller values, turns around and leaves with smaller values again.
(a) there is one point in this graph : at x = -2
(b) and that maximum value at that point is y = 2
