= (x+6) The function f is defined by f(x) 1/2. What f(4) is the value of?
Correct answer: D (parsed from the explanation — this source omits an answer key for this item)
Explanation
= 1 +6 Choice D is correct. It’s given that the function f is defined by f^xh 2^x h. 4 = 1 4+6 4 =5 Substituting 4 for x in the given function yields f^ h 2^ h, or f^ h . Therefore, the value of f^4h is 5. 2 4+6 1 4+6 Choice A is incorrect. This is the value of ^ h, not 2^ h. Choice B is 2+ 4+6 1 4+6 incorrect. This is the value of ^ h, not 2^ h. Choice C is incorrect. This 4+6 1 4+6 is the value of , not 2^ h.
