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.
