5.) Find the value of the sum by expanding the sum. Use proper notation. There are two sides to an equal sign. The Area of the curve is approximately: 6.) Interpret the result: What does the sign tell you about the curve?Riemann Sums Lab Given the function f(x) = xon [-3,1] find the area the region bounded by the curve and the x-axis by letting n = 4 and using the midpoint of each interval. 1.) Graph the function on the interval [-3,1] and shade the region whose area you will approximate. 2.) Divide the interval with their end points. 3.) Find the midpoints of each interval. 4.) Set up the Riemann sum using SIGMA notation and specify the value of A
