49. Listed below are 5 functions, each denoted g(x) and each involving a real number constant c ≥ 2.

If f(x) = 2x, which of these 5 functions yields the greatest value for f(g(x)),for all x > 1?

Answer and Explanation

Your Answer is

Correct Answer is A

Explanation

Because f(x) is a monotonically increasing function, g(x) should be as large as possible. Therefore A.
