Question 1184824

Quadratic regression is a type of multiple linear regression by which the equation of a parabola of '{{{best}}}{{{ fit}}}' is found for a set of data. Draw a second degree polynomial with polynomial regression for the given data set.

A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
{{{ y=ax^2+bx+c}}} where {{{a}}}≠{{{0}}} . 
The best way to find this equation manually is by using the least squares method.
