Find the co-ordinates of the focus, axis of the parabola, equations of the directrix and length of latus rectum of the parabola $y^2=12x$.

Question

$\begin{array}{1 1}(3,0) \quad \text{ x-axis} \quad x+3 = 0 \quad 12 \\ (-3,0) \quad \text{ x-axis} \quad x-3 = 0 \quad 12 \\ (3,0) \quad \text{ y-axis} \quad x-3 = 0 \quad 12 \\(-3,0) \quad \text{ y-axis} \quad x+3 = 0 \quad 12 \end{array} $
