Find the equation of the parabola whose focus is at the point (-1,3) and vertex is at the point (4,3)
***
This is a parabola that open leftward.
Its basic equation: (x-h)^2=-4p(y-k), (h,k)=(x,y) coordinates of vertex.
..
vertex: (4,3)
axis of symmetry:y=3
p=5 (distance from focus to vertex on the axis of symmetry.)
4p=20
equation:(y-3)^2=-20(x-4)
