These results are consistent with our previous findings: a model that predicts ${\tt mpg}$ using a quadratic function of ${\tt horsepower}$ performs better than a model that involves only a linear function of ${\tt horsepower}$, and there is little evidence in favor of a model that uses a cubic function of ${\tt horsepower}$. It is often useful to find the maximum and/or minimum values of functions that model real-life applications. To find these important values given a quadratic function, we use the vertex. If the leading coefficient a is positive, then the parabola opens upward and there will be a minimum y-value.

Let's compare the AIC and BIC values for the linear and the quadratic fit. Without getting too deeply into details, the idea behind these criteria is that we know the model with more parameters (the quadratic model) should achieve a higher maximized log-likelihood than the model with fewer parameters (the linear model).

To find the quadratic functions f (x) = ax^2 + bx + c whose graphs contain the points (1,0) and (3,0) we can evaluate f at 1 and 0 to find \begin {eqnarray*} f (1) &=& a+b+c = 0,\\ f (3) &=& 9a+3b+c = 0. \end {eqnarray*} Solving the first equation for c gives c = -a- b.
