#### Exercise 3

Let W be the area between the graph of  and the x-axis on the interval [1,4].

• Draw W.\item Use a Right-Hand Sum with 3 subintervals to approximate the area of W. Draw W and the rectangles used in this Right-Hand Sum on the same graph.
• Use a Right-Hand Sum with 6 subintervals to approximate the area of W. Draw W 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 W?
