f(x)=x^3/(x^2-1)

find the regions of concavity and inflection points

  • calculus - ,

    Use the 2nd derivative test for that equation to plot out the points where "x" is positive and negative.

    Positive = concave up
    Negative = concave down

    Inflection points exist where the graph moves from concave up to concave down(positive to negative)
