2. Let g(x) = 1 - 2VI. (a) Use GeoGebra to compute s(2) de and write down your answer. 9/2 (b) Below is the graph of y = g(). Use GeoGebra to find the total positive area of the shaded regions (as if you were going to cover them with carpet and needed to know positive areas for both regions). Write down the integral(s) you computed. 2 5 8 9 (c) You should get different answers to parts (a) and (b)! Explain why. 3. Let f(x) = 3x4 - 23 - 2x2 + 5x + 1 and g(x) = 2x - x7. Use GeoGebra to find the exact area (a fraction in lowest terms) of the shaded region in the graph below (just what you see in the window, nothing else). Write down the integral(s) you computed to find your answer. 3 y = f(x) 2 y = g(x) 0.5
