In Exercises 19 and 20, refer to the graphs of the functions f and g in the figure. Assume that the domain of each function is[−3, 3] and that the axes are marked off in one-unit intervals.

(a) Which is larger, f (−2) or g(−2)?

(b) Compute f (0) − g(0).

(c) Which among the following three quantities is the smallest?

(d) For which value(s) of x does g(x) = f(1)?

(e) Is the number 4 in the range of f or in the range of g?
