Answer:
2/3 
Step-by-step explanation:
so the inverse takes us from the range to the domain... they tell us that  f(4) goes to 5.. so if we were to take the inverse  f (5)  it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f
(5)  it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f '(5)  :)
 '(5)  :)

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
