The financial department using statistical techniques, produced the data in Table, where C x is the cost in millions of dollars for manufacturing and selling x million cameras. Table Cost Data Using special analytical techniques (regression analysis), an analyst produced the following cost function to model the Table 6 data: C x = 156 + 19.7 x 1 < x < 15 …… (5) (a) Plot the data in Table 6 . Then sketch a graph of equation (5) in the same coordinate system . (b) Using the revenue function from Example 7(B), what is the company’s profit function for this camera, and what is its domain? (c) Complete Table 7 , computing profits to the nearest million dollars. (d) Plot the data in Table 7 . Then sketch a graph of the profit function using these points. (e) Graph the profit function on a graphing calculator.

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
