m t = - 0.0274 t 7 2 + 7.3873 t 7 + 75.032 The function

Choice B is correct. In the statement "$m\left(330\right)$ 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 $362 \text{kg}$ $330$ days after it was born.

Choice A is incorrect. This would be the best interpretation of the statement "$m\left(362\right)$ is approximately equal to $330$."

Choice C is incorrect. The number $\frac{330}{7}$ 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 "$m\left(362\right)$ is approximately equal to $\frac{330}{7}$."
