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.) W.J y = / (x) 15 10 3 04 14 a.) The area under the curve of f(x) is approximately: b.) Explain the process you went through to arrive at your estimate
