V(t) = 2t^2 - 3t - 3
for an acceleration a(t),
a(t) = d (v(t)) / d t
a(t) = 4t - 3
at t=2
a(2) = 8 - 3
a(2) = 5 feet/s^2
These answers are all the same equation :/ they are all right, they all go right through the point :/
Vertical stretch of 4 and shift of 4 to the right is: g(x) = 4*f(x-4)
So: g(x) = -12(x-4)
You are correct.
The answer is A. He can only work 2 more days with 8 hours a day
