If `f(x)a n dg(x)` are two positive and increasing functions, then which of the following is not always true? (a) `[f(x)]^(g(x))` is always increasing (b) `[f(x)]^(g(x))` is decreasing, when `f(x)<1` (c) `[f(x)]^(g(x))` is increasing, then `f(x)> 1.` (d) If `f(x)>1,t h e n[f(x)]^(g(x))` is increasing.
