There is no constant termbecause fixed costs are not included. Complete parts (a) through (c).

Problem: (the image is attached)

Subparts:

b. Find the least-squares curve of the form above to fit the data (4, 1.57), (6, 2.05), (8, 2.5), (10, 2.7), (12, 3.1), (14, 3.6), (16, 3.8), and (18, 4.35), where x and y represent sales and costs in thousands. Produce a graph that shows the data pts and the graph of the cubic approximation.

y = __x + (__)x² + (__)x³

(round to six decimal places as needed.)

c. (the image is attached)

(round to four decimal places)
