Answer: (1) (2) y = (x - 3)³
D: x ≥ -2 [-2, ∞) D: -∞ < x < ∞ (-∞, ∞)
R: y ≥ -2 [-2, ∞) R: -∞ < y < ∞ (-∞, ∞)
Inc: x > 2 (2, ∞) Inc: (-∞, 3) ∪ (3, ∞)

NOTES:
Domain is the x-values.
Range is the y-values.
From left to right: increasing when going up and decreasing when going down. <em>The anchor and turning point are not considered to be increasing or decreasing.</em>

Acceleration is:
a=g
Velocity is the integral of the above
v=gt+v0
And position is the integral of the above
h=gt^2/2+v0t+h0
You are given that v0=15ft/s and h0=0ft and let g≈-32 so
h(t)=-16t^2+15t
It will hit the ground when h(t)=0 so:
0=-16t^2+15t which is equal to
16t^2-15t=0 factor
t(16t-15)=0, since we are looking for the time other than zero...
t=15/16 of a second :)
So they obviously just rounded to one whole second. So C.) was the correct answer. (Although I would say they are all wrong because they didn't SAY to round the answer :P) Haha, not trying to confuse you, the answer is most likely C. because they had the correct equation.
