Best ResponseYou've already chosen the best response.0a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity ideally follows a curve of this shape.

Best ResponseYou've already chosen the best response.1X  Coordinate of Vertex \[\frac{ b }{ 2a } = \frac{ (24) }{ 2*3 } = \frac{ 24 }{ 6 } = 4\]

Best ResponseYou've already chosen the best response.1The X coordinate for the vertex is b/(2a) = 4 To get the YCoordinate for that X value, plug in x=4 into the original y = 3x^2  24x + 8

Best ResponseYou've already chosen the best response.1well you dont have to do that, if the X coordinate is 4, there is only one choice
