Question:

Suppose the cost C of removing p percent of the particulate pollution from the exhaust gases at an industrial site is given by

where 0 < p < 100.

(a) Use the restriction on p and experiment with a C-range to obtain an accurate graph of the equation with a graphing utility.
(b) Describe what happens to C as p gets close to 100.
(c) The point (98, 396, 900) lies on the graph of this equation. Explain the meaning of the coordinates.
(d) Explain the meaning of the p-intercept.
