Question 203709
y^2-8x=0,,,,we  assume  this  is  problem,,,please  check
.
y^2 =8x,,,,this  is  a  x  parabola,   opening  to  right.
.
basic  form  is,,,,,y^2 =4px
.
fitting  to  our  problem,,,,4p = 8,,,,,p=2
.
Directrix  is  at  x=-p  or  x=-2
.
focus  is  at  (p,0)  or  (2,0)
.
vertex  is  at  (0,0),,,,,{(y-k)^2 =4p(x-h) },,,therefore  h=k=0
.
