Question

The function f is defined by f x = 1 6 x . What is the value of f x when x = 3 ?

Accepted Answer

Choice D is correct. It's given that f x = 1 6 x . Substituting 3 for x in this equation yields f 3 = 1 6 3 , or f 3 = 1 18 . Therefore, when x = 3 , the value of f x is 1 18 . Choice A is incorrect. This is the value of f x when x = 0.5 . Choice B is incorrect. This is the value of f x when x = 1 . Choice C is incorrect. This is the value of f x when x = 1.5 .
