Question

A hammock is a cloth swing as shown in the picture below. The height (y) from ground of any point of the lower curve of the hammock varies with respect to the horizontal distance (x) from some fixed origin. The origin is in the plane of y and x. Consider the following equations and choose the correct option. (It is expected that the hammock does not touch the ground.)

A : y = x2 + 6a + 8
B : y = x2 + 4x + 8
C :y =
= x + 4x + 2
Lower curve of the hammock
O Only A can represent the hammock
O Only B can represent the hammock
Only C can represent the hammock
O Both A and B can represent the hammock
O Both A and C can represent the hammock
O None of these equations is appropriate to represent the hammock
