Question: Axis of the parabola x<sup>2</sup> - 3y - 6x + 6 = 0 is...
Axis of the parabola x2 - 3y - 6x + 6 = 0 is
A
x + 3 = 0
B
y + 1 = 0
C
x - 3 = 0
D
y - 1 = 0
Answer
x - 3 = 0
Explanation
Solution
The equation of axis of the parabola (x - α)2 = 4a(y-β) is x - α = 0.
The given parabola is (x – 3)2 = 3(y+1)
∴The equation is axis is x – 3 = 0.
