A projectile follows a parabolic path whose height, in meters, is given by the function f(x)= -x^2 + 2x + 2 Find the maximum distance that the projectile may cover. |
the vertex is at x=-b/(2a) b=2 and a=-1 x=-b/(2a) x=-2/(2*-1) x=1 so the highest it'll go is at x=1 f(1) = -1^2+2(1)+2 f(1) = 3 the maximum height is 3 meters |
