Question

Tick the correct answer :
In the equation of a parabola x2 = -8y, the coordinates of the focus is :
a.) ( 2,0 )
b.) ( 0,-2 )
c.) ( -2,0 )
d.) ( 0,2 )

Answer 1

b.) ( 0,-2 ) will be the coordinates of the focus is

Step-by-step explanation:

if

X2 = -4ay  focus is (0 , -a )

comparing above equation with

x2 = -8y

a = 2

focus is : (0 , -2 )

Answer 2

Answer: (0,-2) as x²=-8y it is a downward facing parabola.
