Find the equation of the parabola that satisfies the given conditons:
Vertex (0,0) and Focus (-2,0)
The vertex of the parabola is at (0,0) and focus is at (-2,0).
∴y=0⇒ The axis of parabola is along x - axis
So the parabola is of the form y2=4ax.
The required equation of parabola is,
y2=4×−2x⇒y2=−8x
