A point on the parabola whose focus and vertex are respectively at and is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
The general equation of parabola is (y-h)2=4a(x-k) where h,k is the vertex. Given vertex 1, -2 and focus 54, -2. Hence, a=54-1=14 Substituting the value in equation, ⇒(y+2)2=4×14(x-1) ⇒(y+2)2=(x-1) ∴ 10, 1 satisfies the equation.
