Write the standard equation of parabola according to the following conditions: (1) the focal point is f (0,3), (2) the distance from the focal point to the collimator is 2

Write the standard equation of parabola according to the following conditions: (1) the focal point is f (0,3), (2) the distance from the focal point to the collimator is 2

The focus is f (0,3), indicating that the axis of symmetry is on the Y axis
The distance between the focus and the guide line is 2, P = 2,
The focal point is f (0,3), the distance from the focal point to the vertex is p / 2 = 1, and the vertex coordinates of the solvable parabola are (0,2)
The standard equation of parabola is y = 4x ^ 2 + 2
