The given graph shows stopping distances for trucks at various speeds on dry roads and on wet roads. Use this information to solve,
a. Use the statistical menu of your graphing utility and the quadratic regression program to obtain the quadratic function that models a truck’s stopping distance, f(x), in feet, on wet pavement traveling at x miles per hour. Round the x-coefficient and the constant term to one decimal place.
b. Use the function from part (a) to determine speeds on wet pavement requiring stopping distances that exceed 446 feet.
