A = distance of vertex to focus
a = 3
since the parabola is facing at right
the equation will be y^2=4ax
y^2=2(3)x
y^2=6x <=== ANSWER

Since the focus of the parabola is  at  ( 3, 0)   and its vertex at the origin
    the parabola opens to the right of the     Y  axis
     &  the line of symmetry is the   X   axis
  
      the formula  is        y²    =    4px      /  p   =   focal length
                                       y²    =   4*3x
                                the equation is            y²   =    12x
