Given,

 Vertex (0,0) And  focus (3,0)

As vertex of the parabola is (0,0) and focus lies in the positive X-axis, The parabola will open towards the right, And the standard equation of such parabola is 

y^2=4ax

Here it can be seen that a=3

So, the equation of a parabola is 

\Rightarrow y^2=4ax\Rightarrow y^2=4(3)x

\Rightarrow y^2=12x.
