Answer:
Step-by-step explanation:
we know that
In this problem we have a exponential function of the form
where
x ----> is the number of years since 2009
y ----> is the population of bears
a ----> is the initial value
b ---> is the base
step 1
Find the value of a
For x=0 (year 2009)
y=1,570 bears
substitute
so
step 2
Find the value of b
For x=1 (year 2010)
y=1,884 bears
substitute
The exponential function is equal to
step 3
How many bears will there be in 2018?
2018-2009=9 years
so
For x=9 years
substitute in the equation
