A new road is being built along Tall Trees Road. Surveyors have determined the best function to represent the cross-section of Tall Trees Road is

= 0.0008 ( 500)^{2 0.002}+ 300, 0 600, where is the vertical height and is the horizontal distance from the origin.

1. Use a calculator (Hint: set a correct window for your calculator first) to graph the cross-section of Tall Trees Road on your own paper. You may use the grid below as a guide. Clearly label coordinates of the endpoints and the turning point.
