Homework Equations
The equation is f(x) = (x) / (x^2 - 1)
The Attempt at a Solution
Well I first took the derivative, which was f'(x) = -(x^2 - 1) / (x^2 -1) ^2
I set it equal to zero to find the relative extremas, and I got -X^2 -1 = 0, which means X^2 = -1.
That isn't a real number, but so would that mean there are no intervals where it's increasing or decreasing? When I graphed it, it seemed like it was decreasing on all values, negative infinity to positive infinity...
