How do you sketch the graph of #y=-1/4x^2# and describe the transformation?
This is an equation of parabola.
Standard equation of a parabola with Y axis symmetry is given by
Simply rearranging the terms from y=
you can get the standard equation of a parabola
This is a downward opening parabola with negative Y axis as the axis of symmetry.
From the standard equation the co-ordinates of focus are (h,k+p).
So the focus of this parabola is (0,-1).
the vertex is (h,k) => vertex is (0,0)
