Question

ONLY ANSWER IF YOU HAVE THE ANSWER P L E A S E
Use the linear, quadratic, and cubic regression equations determined in example 3 to compare the computed loan balances when when x = 2 with the loan balance amount given in the chart for 2011.

Linear regression equation: y= -6777.54x + 110001.04
Quadratic: y=-251.10x^2 - 2760.02x + 98618.06
Cubic: y: -6.23x^3 - 101.67x^2 - 3747.49x + 100142.23

Answer 1

Answer:

Linear: greater than 2011

Quadratic: lesser than 2011

Cubic: lesser than 2011

Step-by-step explanation:

At x = 2

Linear regression equation:

y = -6777.54(2) + 110001.04

y = 96445.96

More than 2011

Quadratic: y = -251.10(2)² - 2760.02(2) + 98618.06

y = 92093.62

lesser than 2011

Cubic: y = -6.23(2)² - 101.67(2)² - 3747.49(2) + 100142.23

y = 92190.73

lesser than 2011
