Question

The function f is defined by f x = 8 x 3 + 4 . What is the value of f 2 ?

Accepted Answer

The correct answer is 68 . It's given that the function f is defined by f x = 8 x 3 + 4 . Substituting 2 for x in this equation yields f 2 = 8 2 3 + 4 , or f 2 = 8 8 + 4 , which is equivalent to f 2 = 68 . Therefore, the value of f 2 is 68 .
