Use cubic regression to find a function that fits the following points. (-2,-16)(1,5)(3,59)(6,440)

The cubic regression that fits the points , , and is .

Step-by-step explanation:

A cubic polynomial is a polynomial that has the following form:

(1)

Where:

- Independent variable, dimensionless.

- Dependent variable, dimensionless.

, , , - Coefficients, dimensionless.

We construct the following system of equations to determine the coefficients of the cubic regression:

(1)

(2)

(3)

(4)

The solution of the system of linear equations is:

, , ,

The cubic regression that fits the points , , and is .

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

a: inscribed angles
