Find the equation for a parabola with its focus at (5, 0) and a directrix of x = -5.
Parabola opens rightward with vertex at (0,0) :
Its basic form of equation: y^2=4px
For given parabola:
vertex: (0,0)
axis of symmetry: y=0 or x-axis
p=5 (distance from vertex to focus or directrix on the axis of symmetry)
4p=20
Equation of given parabola: y^2=20x
