Consider the graph of a function f(x/ below. Calculate (in any way you wish) an estimate for the total area under that curve, f(x), between x = - 1.0 and x = 2.0 (Note: The area under a curve is defined as the area between the curve and the x-axis. You may wish to begin by shading in the exact area under the curve below.) y = / (1) 15 40 -10 -05 15 20 a.) The area under the curve of f(x) is approximately: b.) Explain the process you went through to arrive at your estimate: c.) How good do you believe your estimate is? Do you believe it is an over-estimate or under- estimate of the exact area? Why? d.) Describe a scenario that this function fx) could be modeling. Within the context of your particular model, describe/interpret what the area under the curve might be representing
