Answer:
Option(A)
Step-by-step explanation:
Given Equation is (x²/4) + (y²/1) = 1.
Option verification:
(A)
Let x = -2,y² = 2.
⇒ (-2²/4) + (2/1)
⇒ -1 + 2
⇒ 1
(B)
Let x = -2, y² = 4.
⇒ (-2²/4) + (4/1)
⇒ -1 + 4
⇒ 3.
(C)
Let x = -2, y² = 6.
⇒ (-2²/4) + (6/1)
⇒ -1 + 6
⇒ 5
(D)
Let x = -2, y = 8.
⇒ (-2²/4) + (8/1)
⇒ -1 + 8
⇒ 7.
Therefore, [-2,2] satisfies the given condition.
Hope it helps!

any method without option verification
It is simple method
ya....got that
but is there any like i hv solved by forming quadratic in cos
by parametric co-ordinates
we can also solve in that way..But it is time talking process
actually my ans is coming (-1,1)
But your answer is not in the options!
ya.... so y I'm not getting that....can u check that once
Do one thing..Post the solution and we can rectify ur mistake!
