79. A file is downloaded to a computer at a rate modeled by the differentiable function f(), where t is the time in seconds since the start of the download and f(1) is measured in megabits per second. Which of the following is the best interpretation of f'(5) = 2.8 ? (A) At time t= 5 seconds, the rate at which the file is downloaded to the computer is 2.8 megabits per second. (B) At time t = 5 seconds, the rate at which the file is downloaded to the computer is increasing at a rate of 2.8 megabits per second per second. (C) Over the time interval 0 sIs 5 seconds, 2.8 megabits of the file are downloaded to the computer. (D) Over the time interval 0 sIs5 seconds, the average rate at which the file is downloaded to the computer is 2.8 megabits per second.
