degree=5 is your answer of your question
Answer:
the must be 3 it couldn't be 10-x.
The practical dominion is from t = 0, when the ball starts motion until the time when the ball hits the ground.
To find the time when the ball hits the ground solve the equation:
h(t) = 0
=> -16t^2 + 68t = 0
Factor: t(-16t + 68) = 0 => t = 0 and -16t + 68 = 0
=> 16t = 68
=> t = 68/16
=> t = 4.25
So, the practical domain is 0 ≤ t ≤ 4.25 s.
Which also may be represented by t ∈ [0, 4.25s]
