In the statement “m^ h is approximately equal to ,” the 330 input of the function, , is the value of t, the elapsed time, in days, since the 362 animal was born. The approximate value of the function, , is the predicted body mass, in kilograms, of the animal after that time has elapsed. Therefore, the 362kg 330 predicted body mass of the animal was approximately days after it was born. Choice A is incorrect. This would be the best interpretation of the statement 362 330 330 “m^ h is approximately equal to .” Choice C is incorrect.
