f(x) = 3

f(x) = x^(2/3)

f(x) = -x^(3/4)

**Steve**, Saturday, August 11, 2012 at 4:55pmif f' > 0, f is increasing. So,

f(x)=3

f' = 0

f is constant everywhere

f(x) = x^(2/3)

f' = 2/3 x^(-1/3)

f' > 0, so f is increasing everywhere

f(x) = -x^(3/4)

f' = -3/4 x^(-1/4)

f' < 0 so, f is decreasing everywhere

rather poor examples, since there are no finite open intervals involved
