points) (a) Please sketch the graph of f (@) = (2 - 1) on [-1, 3] using the grid below. Label at least 3 points on the graph. y Your goal in this problem is to find an upper bound for 3 using Riemann sums. What will your strategy be? 2 O Use a left-hand sum. O Use a right-hand sum. O Break [0, 3] into two intervals and use a left-hand sum on one of them and a right-hand sum on the other. (b) Divide [0, 3] into six subintervals of equal length, then draw the six corresponding rectangles you will use to find an upper bound for / (x - 1)2 dax. Compute the upper bound and show your work. My upper bound is c) Using Wolfram Alpha, Excel or the Geogebra link provided in the LI slides, what new upper bound would you obtain if you divide [0, 3] into 90 subintervals of equal length, using the same strategy you identified in (a)? (Please round to the nearest thousandth.) Answer: My new upper bound is d) What is the exact value of (x-1)2 dx? Show your reasoning, using the Fundamental Theorem of Calculus. My exact answer is
