Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Given: y2+6y-2x+5=0 ⇒y+32=2x+4 ⇒y+32=2x+2 The form: y-k2=4ax-h, where, the vertex is Vh,k Therefore, Vertex ≡-2,-3 Now, 4a=2⇒a=12 Now, we know that focus lies at a distance a from the vertex of the parabola. Therefore, -2+a=-2+12=-32 So, coordinates of…
