The logarithm function that models the time, f(n) , in years is [tex]\rm f(n) = log_{0.98} (\dfrac{n}{74})[/tex], the correct option is D.
What is an Exponential Function?
An exponential function can be represented in the form f(x) = abˣ.
The number of species is decreasing by 0.02
Current number of species = 74
The time f(n) years is given by
f(n) = 74 (0.98)ⁿ
Converting exponent to logarithm form
x = aⁿ
y = logₓ a
f(n) = 74 (0.98)ⁿ
[tex]\rm f(n) = log_{0.98} (\dfrac{n}{74})[/tex]
