Question

The function f is defined by f x = 1 2 x + 6 . What is the value of f 4 ?

Accepted Answer

Choice D is correct. It&rsquo;s given that the function f is defined by f x = 1 2 x + 6 . Substituting 4 for x in the given function yields f 4 = 1 2 4 + 6 , or f 4 = 5 . Therefore, the value of f 4 is 5 . Choice A is incorrect. This is the value of 2 4 + 6 , not 1 2 4 + 6 . Choice B is incorrect. This is the value of 2 + 4 + 6 , not 1 2 4 + 6 . Choice C is incorrect. This is the value of 4 + 6 , not 1 2 4 + 6 .
