2.) The value of a stock, in dollars, 7 minutes after the stock went on sale is given by the function f(t). Answer each question. (1 point each) a.) What are the units of f'(t)? b.) If f(60) = 100 and f '(60) = 14, what is the best guess that you can make at the value of f(58)? c.) If f '(60) = 100 and we have a possible error for our measurements of at most 0.15 cents for every second, what is the maximum error in our function
