Mathematical Methods VCE Units 3 & 4 Practice Question 6a – Inverse Functions

Q6a Mathematical Methods Inverse Functions Unit 3 - AOS 2

A scientist is studying the population of a particular species of insect in a controlled environment. The population, $N(t)$, at time $t$ (in days) is modeled by a function involving both exponential growth and a limiting factor. The scientist also needs to analyze the inverse of this population model to predict when the population will reach certain levels.

Question 6a

3 marks

a. The population of the insect species is modeled by the function $N(t) = 50 + 100e^{-0.1t}$, where $N(t)$ represents the number of insects at time $t$ days. Determine the equation for $t$ in terms of $N$.
