Step 1: Recall the definition of an antiderivative. An antiderivative of a function is another function whose derivative is equal to the original function.
Step 2: Understand that if f(x) and g(x) are both antiderivatives of the same function, their derivatives must be equal to the original function. This implies that f'(x) = g'(x).
Step 3: Use the Fundamental Theorem of Calculus, which states that if two functions have the same derivative, they differ by a constant. This means f(x) = g(x) + C, where C is a constant.
Step 4: Eliminate the other options provided in the problem. For example, f(x) and g(x) do not need to be even functions, linear functions, or identical functions. The only requirement is that they differ by a constant.
Step 5: Conclude that the correct relationship between f(x) and g(x) is that they differ by a constant, i.e., f(x) = g(x) + C.
