Answer:
Explanation:
a) The function f(t) that models the number of bears t years after 2012 can be expressed using exponential decay, as follows:
f(t) = 965 * (0.98)^(t)
Where 0.98 represents the rate of decline of 2% per year. The starting point for t is 0, which corresponds to the year 2012.
b) To find the population of bears predicted to be in 2020, we need to evaluate f(8) since 2020 is 8 years after 2012:
f(8) = 965 * (0.98)^(8)
= 834.84 (rounded to two decimal places)
Therefore, the predicted population of bears in 2020 is approximately 835.
