A parabola in the form
of (x-h)^2=4c(y-k) turns up or down. When 4c
is a
negative number, the
parabola turns down,
but if 4c is positive, the parabola
turns up. (h,k)
represents the vertex
of the parabola. A
parabola in the form of (y-k)^2=4c(x-h) turns right or left. If 4c
is positive
the parabola turns right, but if
4c is negative the parabola turns left. The
focus is located c units from the vertex and the latus rectum is 4 times this
distance.
