Take derivative..
f'(x) = 3*2*(x+4)
f'(x) is must be equal to 0.
6*(x+4)=0
x=-4
for x=-4; what is the y value?
for x=-4; f(x)=-5
the vertex is (-4,-5)<span />

Answer:

Step-by-step explanation:
You have the following functions:

Therefore
indicates that you must divide both functions, as you can see below:

Simplify it. Therefore, you obtain:

Answer:
Step-by-step explanation:
1. No it does not as the rock will accelerate downwards (because of gravity) but we can also see that at the first second the rock fell 16 feet compared to the 2 to 3 seconds gap where it fell 80 feet (144-64).
2. All the way down to the ground. Each time gap is getting bigger and bigger (it's accelerating) and the gap between 5 and 6 s should be bigger than 4 to 5 and it is not as the rock cannot fall through the ground but only hit the ground
you may have to change the english a bit and english is not my first language
hope this will help
-1 C, that's the only logical answer I can think of. Or does it have to be in F?
