Find the exponential function that passes through the points (−10/13 , 6) and (14 ,1/10). Round the numbers in your final answer to three decimal places each.

You add 6 paramecia to a test tube and feed them bacteria. One week  later the population has grown to 15. Assuming that the population is growing exponentially, how many paramecia can you expect after 7 weeks? Round your answer to the closest full number.

A radioactive substance decays exponentially. A scientist begins with 160 milligrams of a radioactive substance. After 32 hours, 80 mg of the substance remains. How many milligrams will remain after 36 hours? mg
