1. Find f'(x) and f''(x) if f(x)=5^x
2. Marginal profit is 100-2q. If the profit is $700 when q=10, find the:
a: profit function P(q)
b: What is the maximum profit?
3. f(t)=(t^2)(e^-2t) Find the absolute max and min values of f(t) on the interval -1<=t<=2 (and equal to) Hint: there are 2 critical values for this function
