This should be explained in your book. Show your work if you have any problems.
Originally Posted by kenzie103109 find the vertex, focus, and directrix of the parabola and sketch its graph x + y^2 = 0 as mentioned since and then you have a vertex at so now we have the equation of here so Focus at so Directix at so is the Directix note some books use versus as the variable
