Follow-up Question

Is this answer correct? It seems as if you mention that 2^(f(n)) is always an upper bound for 2^(c*g(n)), which is not right consider the statement (should be the other way around). Also, how does this statement, "Since 2 f(n) is an exponential function with a positive base, it grows much faster than any polynomial function g(n)." give us any inference on the upper bound?
