The temperature of a room, in degrees Fahrenheit is modeled by H, a differentiable function of the number of minutes after the is adjusted. Of the following, which is the best interpretation of H degree (S) = 2? The temperature of the room is 2 degrees Fahrenheit, 5 minutes after the is adjusted. The temperature of the room increases by 2 degrees Fahrenheit during the first 5 minutes after the is adjusted. The temperature of the room is increasing at a constant rate of 2/5 degree Fahrenheit per minute. The temperature of the room is increasing at a rate of 2 degrees Fahrenheit per minute, 5 minutes after the is adjusted.
Explanation / Answer
