A marketing specialist determines that when a certain product is released, the number of social media references to it can be modeled by f(t) = 750 + 5log3(t) where t is the number of days since the release. a.) Determine f' (t) = b.) Determine f' (19) rounded to 5 decimal places. f'(19) = c.) Which of the following is the best interpretation of f(19) = 763 (with f(19) is rounded to the nearest whole number)? After 19 days, there are 763 references. d.) Which of the following is the best interpretation of f'(19) (with f'(19) is rounded to the nearest whole number)?
