You can put this solution on YOUR website!
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.
\n" ); document.write( ":
\n" ); document.write( "1. Write a function that models the change in animal population.
\n" ); document.write( "a 3.5% reduction each year means we have 96.5% of the previous year
\n" ); document.write( "where x = no. of years, y = animal population
\n" ); document.write( "f(x) = 80*(.965^x)
\n" ); document.write( ";
\n" ); document.write( "2. Write the function that models exponential growth or decay
\n" ); document.write( "the above is an exponential decay equation
\n" ); document.write( ":
