AP EAMCET · Maths · Parabola
If \(x+5=0\) is the directrix and \((-3,0)\) the vertex of a parabola, then equation of this parabola is ____
- A \(y^2=8(x+3)\)
- B \(y^2=8(x-3)\)
- C \(x^2=8(y+3)\)
- D \(x^2=8(y-3)\)
Answer & Solution
Correct Answer
(A) \(y^2=8(x+3)\)
Step-by-step Solution
Detailed explanation
Given parabola is, So, its equation is, \(y^2=4 a(x-(-3)\) Where \(a=2\) units. \(\therefore \quad y^2=8(x+3)\)
