Two exponential functions are shown in the table. Which conclusion about f(x) and g(x) can be drawn from the table? X Х f(x)=2* 1 2 g(x)= 2 4 1 4 O The functions f(x) and g(x) are reflections over the x- axis. O The functions f(x) and g(x) are reflections over the y- axis. O The function f(x) is a decreasing function, and g(x) is an increasing function. The function f(x) has a greater initial value than g(x). 1 1 2 1 2 1 0 -1 1 2 1 2 --2 4 1 4
