A small town has a stray cat problem. Currently it is estimated that there are 120 stray cats in the town, and the population grows at a rate of 3% per year. Since the rise of the stray cat population, the rat population has decreased significantly, decreasing by 4% per year. The estimated population of rats is 3000. O a) Determine a function that models the population of cats each year. O b) Determine a function that models the population of rats each year. O c) Determine when the cat and rat populations will be equal. O d) Do you think that these functions appropriately model these populations? Why or why not
