Solution

(a). The graph shows x-values from -3 to 4. Also, there is no hole in the graph. Hence the domain of f is [-3,4].

(b). The graph shows y-values from -2 to 2. Also, there is no hole in the graph. Hence the range of f is [-2,2].

(c ). When x = 1, f(x) = 0. Hence f(1) = 0.

(d). f(x) = 1 when x = -1, or, x = ½ or, x = 2. Hence theanswer is -1,1/2,2.

(e). f(x)> 1,when x (-1,1/2) or, when x (2,4]. Hence f(x)> 1 when x((-1,1/2)U(2,4].
