The equation of directrix of parabola \(x^2+8 x+12 y+4=\) 0 is
- A \(y+4=0\)
- B \(y-1=0\)
- C \(y-4=0\)
- D \(y-2=0\)
Answer & Solution
Correct Answer
(C) \(y-4=0\)
Step-by-step Solution
Detailed explanation
Given parabola is \(x^2+8 x+12 y+4=0\) This can be written as \((x+4)^2=4(-3)(y-1)\) Here, \(V=(-4,1)\) and equation of Directix, \(Y=4\) or \(y-4=0\)
