\n" ); document.write( "7. A basketball is tossed from the top of a 3-m wall. The path of the basketball is defined by the relation y=-x^2+2x+3, where x represents the horizontal distance travelled, in metres, and y represents the height, in metres, above the ground. How far has the basketball travelled horizontally when it lands on the ground?\r
