    Increasing/Decreasing Intervals of Slope for Rational Functions

    For the function y=1/(x^2+1) , when is the slope increasing and decreasing?

    How do you tell for this graph, since at the left side it's first increasing, then slowly decreasing(and on the right, vice versa)?

    This seems to me to be a Calculus question.

    Kind of, but can you tell without using calculus?

    Yes, if an estimate is all that's wanted, fine.
