Using a calculator and considering the given data, the quadratic regression equation that best fits the given data is:

y = -0.002x² - 2.051x + 31.179

How to find the equation of quadratic regression using a calculator?

To find the equation, we need to insert the points (x,y) in the calculator of quadratic regression.

In this problem, the points to be inserted are as follows:

(0, 31), (1,29), (2, 28), (4,22), (6,19), (10, 11), (11,8).

Inserting these points, the equation is given by:

y = -0.002x² - 2.051x + 31.179
