1. The population of frogs in a park is decreasing exponentially at a rate of 2% each year. In the year 2006, the population was estimated to be 4800.
2. Use the exponential decay formula to write an equation to model the situation.
3. Use your equation from Part (a) to predict the frog population in the year 2018.
4. Sketch the graph of the equation you wrote in Part (a). Find its asymptote, domain, and range.
