Draw a picture!

First, plot the function 1/x on the interval [1,2].

What the question is asking is for you to draw 5 rectangles of equal width 'under' the curve. So the base of the first rectangle will go from 1 to 1.2, the second from 1.2 to 1.4, and so on.

For the upper sum, the height of each rectangle will be the value of the function evaluated at the left-most part of the rectangle.
