Find the equation of the parabola that satisfies the given conditions: Vertex (0,0); focus (–2,0)


Since the vertex is at (0,0) and the focus is at (- 2, 0) which lies on x-axis, the x-axis is the axis of the parabola. Therefore, equation of the parabola is of the form

y2 = - 4ax ⇒ y2 = - 4(2)x = - 8x
