Question

Find the standard form of the parabola with the given characteristic and veretx at the origin directrix: x = 5

Answer 1

so the origin is the vertex, and the directrix is at x = 5
in a parabola the focus and the directrix have equal distance from the vertex
so if the directrix is 5 units from the vertex
the focus is 5 units also from the vertex in the opposite direction
that also means that the parabola is a horizontal axis type like
