Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers z for which f (x) is a real number. Let f be the function defined by f (x) = bounded by the graph of f and the x-axis. (a) Find the area of R. -2 2- 1 (x+2) for 2 < < 0 2-2 sin for 0 2 The graph of f is shown in the figure above. Let R be the region
