1. Find the maximum profit and the number of units x that must be produced and sold in order to yield the maximum profit. The revenue function is () = 2 + 110 + 60. The cost function is () = 1.12 + 10 + 80.

2. se implicit differentiation to find /dx. Then, find the slope of the curve at the given point.

^3 + ^3 = 9; (1,2)

3. Use Calculus to find the absolute maximum and the absolute minimum of the function

over the indicated interval. ()=^3+^2+1; [2,1/2]

4. An investment is made at 3.95% per year, compounded continuously. What is the doubling time?
