Q2 of 27 Page 11

Find the coordinates of the focus, axis, the equation of the directrix and latus rectum of the parabola y2 = 8x.


Consider y2 = 8x,


Here axis of symmetry is x- axis.


Comparing with y2 = 4ax


4ax = 8x


a = 2


So, focus is (2,0) and equation of directrix is x = -2.


Length of latus rectum = 4a


= 8
