profit in millions of dollars.
(a) Use your calculator to fill out the following
P(3)
table and graph the function on the grid for the
interval 0 SX S10
P(x)

(b) Over what interval is P(x) <0? What does this
interval represent?
(e) Evaluate P(O). What might this stand for?
(d) Explore the table to determine the value of x for
which P(x) = 0. What might this stand for?
