Let f : [0, ∞) → [0, ∞) and g : [0, ∞) → [0, ∞) be non-increasing and non-decreasing functions and h(x) = g[f(x)]. If f and g are differentiable for all points in their respective domains and h(0) = 0, then the value of h(3) is……
Dear student, Increasing Functions A function is "increasing" if the y-value increases as the x-value increases, like this: It is easy to see that y=f(x) tends to go up as it goes along. Flat ? What about that flat bit near the start? Is that OK?
