Question 946039
A.) The population of a certain animal species decreases at a rate of 3.5% per year. You have counted 80 of the animals in the habitat.
:
1. Write a function that models the change in animal population.
a 3.5% reduction each year means we have 96.5% of the previous year
where x = no. of years, y = animal population
f(x) = 80*(.965^x)
;
2. Write the function that models exponential growth or decay
the above is an exponential decay equation
