What are the intervals where f(x) is increasing and decreasing: f(x)=\(\frac{x}{\sqrt{x^2+1}}\)
What are local max/mins, and where is it concave up and down??
Intervals increasing : (-infinity, infinity)
Intervals decreasing: none
local max : none
local min : none
no local max/min because f(x) is always increasing
intervals concave up : (-infinity, 0)
intervals concave down: (0, infinity)
