Write the equation of the parabola with vertex at (0,0) given the following information. Then graph.

Question

Focus at (6.0)

p =

opens =

directrix =

Answer 1

p = 6, p is the distance between the vertex and the focus

opens = up, it will open toward the focus

directrix = y=-6, It will be p units on the other side of the vertex. Since this opens up, it will be a horizontal line y=constant
