preferring all lower case,





With this, if you compare to (x-h)^2=4p(y-k), then p=1, or the focus and directrix each is 1 unit from the vertex;
and
for your example,
====================================================================
vertex (2,3)
parabola is with vertical symmetry axis with vertex as minimum;
focus (2,4)
directrix y=2
====================================================================
