In July 2005, professional skateboarder Danny Way jumped over the Great Wall of china. His path can be modelled by the relation h = −0.05d 2 + 1.15d , where h is his height above the Great Wall and d is his horizontal distance from the take-off ramp, both in metres. Factor this function. Determine the distance between Danny's take-off and landing. What was Danny’s maximum height above the Great Wall?
