Use the given graphs of f and g to estimate the value of f(g(x)) for x = -5, -4, ..., 4, 5.

this is the graph http://img407.imageshack.us/img407/1121/1352bw0.th.gif

(a) f(g(-5)) =
(b) f(g(-4)) =
(c) f(g(-3)) =
(d) f(g(-2)) =
(e) f(g(-1)) =
(f) f(g(0)) =
(g) f(g(1)) =
(h) f(g(2)) =
(i) f(g(3)) =
(j) f(g(4)) =
(k) f(g(5)) =
