Answer:
Where t represent the time in years
For this case this model follows the general model given by:
Where a = 140 represent the initial amount of bisons and y the number of bisons after t years and b = 2.7 represent the growth rate
For this case we want to find the value of y when t =30, and if we replace the value of t =30 in our function we got:
And if we round to the nearest whole number we got 189 bisons after 30 years
Step-by-step explanation:

Answer:
The range and domain of this function is [-2, 2]
Step-by-step explanation:
For the domain it must be fulfilled that . Then,
. This expression is true for the values of
that make the factors simultaneously non-negative or non-positive.
Case non-negative factors
implies that
, that is
implies that
, that is,
. The intersection of the previous sets is [-2, 2].
Case non positive factors
implies that
, that is
implies that
, that is,
. The intersection of the previous sets is empty.
Then the domain of the function is [-2, 2]
The range of this function is the domain of its inverse. The inverse of the function is itself, so the range is [-2, 2]
