"b" represents the population of bobcats.

1) "t" represents the number of years after 2008.

2) The domain (t) starts at 0 (which is the year 2008) ⇒  t ≥ 0

3) The range (b) starts when t = 0. b =-0.32(0)² + 2.7(0) + 253 ⇒ b ≥ 253

4) The graph is discrete because the population must be in whole numbers.
