Homework Statement
It asks for any Points of Inflection
The second derivative is given: y'' = (2x^5 + 4x^3 - 6x) / (x^2-1)^4
Homework Equations
The original function was x / (X^2 -1)
The Attempt at a Solution
I have set it equal to zero, and I get 2x^5 + 4x^3 - 6x = 0
I then simplified, taking out the 2, as well as factoring out an x
leaving me with
x(x^2 + 3)(x^2 -1)...
I get a weird answer though...x^2=-3 does not exist...and x = =+-1, are vertical asymptotes in the original function
help?
