4. Graphing Natural Base Functions ** Because a = 3 (it is positive) and r = 1 (also positive), this is an exponential growth function. ** Use a table of values to graph the function. X-201 Y

5. Graphing Natural Base Functions ** Because a = 1 (it is positive) and r = -0.5 (negative), this is an exponential decay function. ** Use a table of values to graph the function. X-4-202 Y Why did I choose different x values t his time?

6. Solving Real Life Problems

7. Your friends account has a balance of about $7,300 after 10 years. Since when t=0 the balance is 4000, your principal is greater than your friends because you started with 4500. Your friend has a greater balance after 10 years.
