Accepted Answer

Choice A is correct. It's given that the function f x = 200,000 1.21 x gives a company's predicted annual revenue, in dollars, x years after the company started selling light bulbs online. It follows that f x represents the company's predicted annual revenue, in dollars, x years after the company started selling light bulbs online. Since the value of f 5 is the value of f x when x = 5 , it follows that " f 5 is approximately equal to 518,748 " means that f x is approximately equal to 518,748 when x = 5 . Therefore, the best interpretation of the statement " f 5 is approximately equal to 518,748 " in this context is 5 years after the company started selling light bulbs online, its predicted annual revenue is approximately 518,748 dollars. Choice B is incorrect and may result from conceptual errors. Choice C is incorrect and may result from conceptual errors. Choice D is incorrect and may result from conceptual errors.
