Question
Hello there, can you help me solve the problem with two subparts (b and 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
c. (the image is attached)

Transcribed Image Text:c. If a machine learned the curve you found in (b), what output would it provide for an
input of x = 13?

Transcribed Image Text:A simple curve that often makes a good model for the variable cost of a company, as a
2
function of the sales level x, has the form y =B₁x + ß₂ײ + ß3׳. There is no constant term
because fixed costs are not included. Complete parts (a) through (c).
