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 = x^2 + 6x + 8
B: y = x^2 + 4x + 8
C: y = x^2 + 4x + 2

a. Only A can represent the hammock.
b. Only B can represent the hammock.
c. Only C can represent the hammock.
d. Both A and B can represent the hammock.
e. Both A and C can represent the hammock.
f. None of these equations is appropriate to represent the hammock.

Answer 1

Answer:

option c only C can represent the hamlock

Answer 2

Answer:

b.Only B can represent the hammock

Step-by-step explanation:

As per given condition It is expected that the hammock

does not touch the ground.

So for any value of X = ?

Y must me y>0

when we solve the equation  for A, B and C

we get that for A and C the value of Y is less than zero y<0

for some x value less then -3
