# CCGPS AG 5.1.2 Example 4

A car’s total stopping distance in feet depends on many factors, but can be approximated by the expression $\frac{11}{10}x + \frac{1}{19}x^2$, for which $x$ is the speed of the car in miles per hour. Is this expression quadratic? What effect does doubling the car’s speed from $10$ mph to $20$ mph have on the total stopping distance?
