OG详解-OG2 数学1 Q16

Choice A is correct. The function f gives the area of the rectangle, in ft², if its width is w ft. Since the value of f(14) is the value of f(w) if w =14, it follows that f(14)=1,176 means that f(w) is 1,176 if w =14. In the given context, this means that if the width of the rectangle is 14 ft, then the area of the rectangle is 1,176 ft².
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 interpreting f(w) as the width, in ft, of the rectangle if its area is w ft², rather than as the area, in ft²，of the rectangle if its width is w ft.
