You can put this solution on YOUR website! Find the equation in standard form of the parabola with the directrix x=-2 and focus (4,3)
parabola opens right
Its basic form of equation: (y-k)^2=4p(x-h), (h,k)=coordinates of vertex
vertex: (1,3)
axis of symmetry: y=3
p=3 (distance from vertex to either directrix or focus on the axis of symmetry)
4p=12
equation: (y-3)^2=12(x-1)
