Question

{(1, 1), (-3, 6), (-5, 4)}

Use technology to find the quadratic regression curve through the given points. HINT [See Example 5.] (Round all coefficients to four decimal places.)

Answer 1

The quadratic regression curve for a set of points is calculated using a graphing calculator or software that performs this task. These devices use the given points to produce a quadratic equation of the form y = ax^2 + bx + c. The coefficients a, b, and c are usually rounded to four decimal places.

Step-by-step explanation:

To calculate the quadratic regression curve for this set of points, we would use a graphing calculator or software that performs this task such as Desmos, Excel, or online quadratic regression calculators. Typically this involves inputting the given points {(1, 1), (-3, 6), (-5, 4)} into the program. The quadratic equation produced by the software would take on the form y = ax^2 + bx + c. Here 'a', 'b', and 'c' are the coefficients obtained from the quadratic regression and are usually rounded to four decimal places. However, without the actual software, I can't provide the specific coefficients right now.
