The vertex of a parabola is the point (a,b) and latusrectum is of length `l`. If the axis of the parabola is along the positive direction of y-axis, then its equation is : (A) `(x+a)^2=l/2(2y-2b)` (B) `(x-a)^2=l/2(2y-2b)` (C) `(x+a)^2=l/4(2y-2b)` (D) `(x+a)^2=l/8(2y-2b)`

The vertex of a parabola is the point (a, b) and latus-rectum is of length l. If the axis of the parabola is along the positive direction of y-axis, then its equation is

The vertex of a parabola is the point (a,b) and latusrectum is of length 1. If the axis of the parabola is along the positive direction of y-axis then its equation is

The vertex of a parabola is the point (a , b) and the latus rectum is of length ldot If the axis of the parabola is parallel to the y-axis and the parabola is concave upward, then its equation is (a) (x+a)^2=l/2(2y-2b) (b) (x-a)^2=l/2(2y-2b) (c) (x+a)^2=l/4(2y-2b) (d) (x-a)^2=l/8(2y-2b)

The vertex of a parabola is the point (a , b) and the latus rectum is of length l . If the axis of the parabola is parallel to the y-axis and the parabola is concave upward, then its equation is a. (x+a)^2=1/2(2y-2b) b. (x-a)^2=1/2(2y-2b) c. (x+a)^2=1/4(2y-2b) d. (x-a)^2=1/8(2y-2b)

The vertex of a parabola is the point (a,b) and the latus rectum is of length l .If the axis of the parabola is parallel to the y-axis and the parabola is concave upward,then its equation is (x+a)^(2)=(1)/(2)(2y-2b)(x-a)^(2)=(1)/(2)(2y-2b)(x-a)^(2)=(1)/(8)(2y-2b)(x-a)^(2)=(1)/(8)(2y-2b)

The axis of a parabola is along the line y=x and the distance of its vertex and focus from the origin are sqrt(2) and 2sqrt(2) , respectively. If vertex and focus both lie in the first quadrant, then the equation of the parabola is (a) (x+y)^2=(x-y-2) (b) (x-y)^2=(x+y-2) (c) (x-y)^2=4(x+y-2) (d) (x-y)^2=8(x+y-2)
