The graphs of the revenue and cost functions for the production and sale of x units are shown below. The cost function is the straight line, and the revenue function is the curve.
a. Use the graph to estimate the production level x that maximizes profit. Use only values that appear on the horizontal axis for your estimation.
x = units
b. What are the points (x, C(x)) and (x, R(x)) on the graphs of the cost and revenue functions corresponding to the value of x that maximizes profit?
(x, C(x)) =
(x, R(x)) =
c. What is the maximum profit? $
d. If the cost per unit decreases, should the production level be raised or lowered to maximize profit?
