a. For graph of f(x) = 4 - x2 shown below, use a straight edge to draw the rectangles for a right hand Reimann sum with 4 subintervals using a straight edge. 4 2 b. Calculate the Reimann Sum . i.e. R4 c. Set up the definite integral to find the exact area under the curve f(x) on the interval [0,2] and then use the Fundamental Theorem of Calculus to find the exact area
