Homework Statement
Use the first derivative to determine where the graph of y = x/(x^2+1) is rising.
Homework Equations
The Attempt at a Solution
Ive figured the derivative to be (1-x^2) / (x^2+1)^2 and I know that the derivative > 0 will tell me where the graph is rising. I am just not sure how to figure that out. Do I need to simplify my derivative a bit more to make it work?
