1. Define -3+ 4-x2 if -2 x 2 f(x) = x-5 if x 2. (a) Graph f from x = -2 to x = 8. (b) Compute f(x) dx using the geometric interpretation of the integral and commonly 2 known area formulas. Your work should make clear what regions you consider when computing your answer; indicate these regions in your diagram for (a).
