4) Review other projects and respond. Choose at least two of your classmate's projects. a) Algebraically find the inverse to the function given in Question 2. Identify an additional characteristic of inverse functions not given by your classmate. (9pts) b) Calculate the total amount your classmate will have in the bank based on the situation given. Then, change the interest rate (keeping the other parameters the same) and recompute. Comment on your findings. (9pts)\f1 .
