# How do you find the inflection points of the graph of the function: #(1-x^2)/x^3#?

##### 1 Answer

An inflection point is a point on the graph at which concavity changes. So, it is a point on the graph at which the sign of the second derivative changes.

#### Explanation:

These key numbers cut the number line into 4 intervals.

We look at the sign of

The arithmetic is left as an exercise. (But note that
