Question

equation of the parabola with focus at (2,0) directrix is x+2=0 is :
a. y^2=4x
b. y^2=12x
c. y^2=8x
d. y^2= -4x​

Answer 1

Answer:

your ans is-:c

Step-by-step explanation:

since focus lies in x-axis

hence equation is either y^2=4ax or y^2=-4ax

now focus has positive X co- ordinate

so, we have to use eqn. y^2=4ax

coordinates of focus (a,0)

(2,0)=(a,0)

hence

a=2

required equation is

y^2=4ax

y^2=4 * 2 * X

y^2=8x.
