Answer:
9.5
Step-by-step explanation:
To solve this you need to use PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction).
PEMDAS is the order in which you need to do the problem. First, do the work within the parentheses. Then, do as the exponent require. After that, multiply as stated. After all of this, you add in the end.

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
