Best ResponseYou've already chosen the best response.1what is the distance from the vertex to the focus..?

Best ResponseYou've already chosen the best response.1great that distance is called the focal length the focus is to the right of the vertex so the parabola is concave right dw:1434090472682:dw so a general form of this parabola is \[(y  k)^2 = 4a(x  h)\] where (h, k) is the vertex and a is the focal length... so any thoughts on the equation... after you substitute what you know...?
