a) We are looking for the places where f has a relative maximum value. This means that the graph changes from increasing to decreasing, peaking at one point. The maxima of is x = 1

b) The minimum is the opposite. It is where the graph changes from decreasing to increasing. This graph has two minima at x = 0 and x = 2.

Try this:
Use the graph...
(a) max. is in point (1;5);
(b) min. are in points (0;1) and (2;1).

(a) the number(s) at which...
in the point (1;5).
P.S. if it is possible, check max. in other sources, this point is chosen using property of f '.
