The following figure shows the graph of a function h.

(a) Find h(a), h(b), h(c), and h(d).

(b) Is h(0) positive or negative?

(c) For which values of x does h(x) = 0?

(d) Which is larger, h(b) or h(0)?

(e) As x increases from c to d, do the corresponding values of h(x) increase or decrease?

(f) As x increases from a to b, do the corresponding values of h(x) increase or decrease?
