The length (in centimeters) of a typical Pacific halibut t years old is approximately

f(t) = 210(1 − 0.94e^−0.2t).

(a) What is the length of a typical 9-year-old Pacific halibut?

cm

(b) How fast is the length of a typical 9-year-old Pacific halibut increasing?

cm/yr

(c) What is the maximum length a typical Pacific halibut can attain?

cm

a) plug in t=9

b) take the derivative

c) as t gets larger, e^-.2t gets smaller

so .94e^-.2t gets smaller

so you are left with

f(t) = 210(1 - 0) = 210
