In Exercise, treat the given nonlinear functions as linear functions in order to sketch their graphs. At times, this can he useful in showing certain values of a function. For example, y = 2 + 3x2 can be shown as a straight line by graphing y as a function of x2. A table of values for this graph is shown along with the corresponding graph in Fig. 1.

x	0	1	2	3	4	5
x2	0	1	4	9	16	25
y	2	5	14	29	50	77

The force F (in lb) applied to a lever to balance a certain weight on the opposite side of the fulcrum is given by F = 40/d, where d is the distance (in ft) of the force from the fulcrum. Sketch F as a function of 1/d.
