Write the equation of a parabola with a vertex at (0, 0) and a focus at (-4, 0).
This is an equation of a parabola that opens leftward with vertex at the origin.
Its basic equation: y^2=-4px
axis of symmetry: y=0 or x-axis
p=4 (distance from vertex to focus on the axis of symmetry)
4p=16
equation: y^2=-16x
