Question: The vertex of the parabola y<sup>2</sup> = 4(a´ – a)(x – a) is-...
The vertex of the parabola y2 = 4(a´ – a)(x – a) is-
A
(a´, a)
B
(a, a´)
C
(a, 0)
D
(a´, 0)
Answer
(a, 0)
Explanation
Solution
y2 = 4(a´ – a)(x – a) ...(1)
(y – y1)2 = 4a1(x – x1) ..(2)
compare the equation (1) & (2)
so, vertex A(x1, y1) = (a, 0)
