Answer: The graph crosses the x-axis at x = 2.
Step-by-step explanation:
The root has a multiplicity of 3, meaning that it crosses the x axis at x=2.
Consider the figure shown on the coordinate plane. What are the coordinates of the midpoint of line segment CB?

The given model would make the least sense to use for x=-2.75.
the given function is:
a quadratic relationship,
where
h is the height in feet
x is the time in seconds
<h3>what is kinetic energy?</h3>Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.
h(-2.75) =
h(0.25) =
h(1.75) =
h(25) =
therefore, x=-2.75 this model would make the least sense to use
