(y-k)^2=4p(x-h) so we have a parabola that opens left or right p is distance from vertex to focus ok, so if p is positive, tehen it opens to the right the focus is to the right of the vertex
s
(y-3)^2=4(2)(x-5) vertex is (5,3) 2 is positive so focus is to the right of vertex it is 2 units from vertex (5,3), move to right 2 units is 5+2=7 (7,3) is focus
