OG详解-OG9 数学2 Q56

Choice B is correct. In the statement “m(330) is approximately equal to 362,” the input of the function, 330, is the value of t, the elapsed time, in days, since the animal was born. The approximate value of the function, 362, is the predicted body mass, in kilograms, of the animal after that time has elapsed. Therefore, the predicted body mass of the animal was approximately 362kg 330 days after it was born.
Choice A is incorrect. This would be the best interpretation of the statement “m(362) is approximately equal to 330.” Choice C is incorrect. The number 3307​​ is the number of weeks, not the number of days, after the animal was born. Choice D is incorrect. This would be the best interpretation of the statement “m(362) is approximately equal to3307​​.”
