I think the answer is A
Hope it helps :-)
X divided by two is 5
So you multiply 5 and 2 to get 10. Therefore x equals 10
This is how i worked it out.
Good Luck
The domain is the limits of the function. Since time doesnt go negative, start with 0. At time 0, the height is
-16(0)^2 + 144 = 144ft
Then, solve for t to find the upper limit for t, which is when the height is zero (since you're dropping the object).
-16t^2 + 144 = 0
-16t^2 = -144
t^2 = 9
t = sqrt(9)
t = 3
The domain is 0 to 3 seconds.
