find the regions of concavity and inflection points

- calculus -
**Anonymous**, Tuesday, November 25, 2008 at 8:41pmUse 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)
