dear anmol
on putting x=0 , we have
y2+4y+4=0
(y+2)2 = 0
y=-2 only 1 value of y that means it touches y axis ...
now at y=0 , we have
x2-8x+4 = 0
here we have 2 reaL values of x , that means it cuts the x axis at two points ..
so option b is correct
DO YOU KNOW THAT COORDS OF CENTRE OF CIRCLE ARE {-1/2 COEFF. OF X ,-1/2 COEFF. OF Y}
RADIUS OF CIRCLE [X1,Y1] IS UNDER ROOT OF X1^2 +Y1^2 -C
FOR THIS EQUATION COORDS ARE [4,-2]
N RADIUS IS 4
SO IT WILL TOUCH Y AXIS AS ABSICCA =RADIUS
