Exercise 2

Let S be the area between the graph of y = f ( x ) = 2x and the x-axis on the interval [1,6].

  • Draw S. 
  • Use a Right-Hand Sum with 2 subintervals to approximate the area of S. Draw S and the rectangles used in this Right-Hand Sum on the same graph.
  • Use a Right-Hand Sum with 5 subintervals to approximate the area of S. Draw S and the rectangles used in this Right-Hand Sum on the same graph. 
  • Are your approximations in parts (b) and (c) bigger or smaller than the actual area of S?
