The table shows the approximate height of an object x seconds after the object was dropped. The function h(x) = –16x2 100 models

gregori [183]

The given model would make the least sense to use for x=-2.75.

the given function is:

$h(x)= -16x^2 +100$

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.
