The graph shows stopping distances for motorcycles at various speeds on dry roads and on wet roads.model a motorcycle’s stopping distance, f(x) or g(x), in feet, traveling at x miles per hour. Function f models stopping distance on dry pavement and function g models stopping distance on wet pavement.

a. Use function g to find the stopping distance on wet pavement for a motorcycle traveling at 35 miles per hour. Round to the nearest foot. Does your rounded answer overestimate or underestimate the stopping distance shown by the graph? By how many feet?

b. Use function f to determine speeds on dry pavement requiring stopping distances that exceed 267 feet.
