The population of bobcats in northern arizona since 2008 can be modeled using the function b(t) = –0.32t2 + 2.7t + 253.
what does t represent?
what is the domain for this function?
would the graph be continuous or discrete, and why?

A) t represents time ( in years ) since 2008( 2008 is zero-year)
B) Domain for the square function is x∈R, but for this kind of function there are only positive values. Firs we will find interceptions with x-axis :


(calculate), t1=-24.22,  t2=32.65
Domain for this function is:  0 ≤ t ≤32.65 
C) The graph is discrete, because it is only in the first quadrant ( doesn`t have negative values ( i.e. you can`t have -10 bobcats in northern Arizona.
