## How do you find inflection points on a graph?

## What do points of inflection look like?

Inflection points are points where the function changes concavity, i.e. from being “concave up” to being “concave down” or vice versa. In similar to critical points in the first derivative, inflection points will occur when the second derivative is either zero or undefined.

## How do you write an inflection point?

## How do you find concavity and inflection points?

**How to Locate Intervals of Concavity and Inflection Points**

- Find the second derivative of f.
- Set the second derivative equal to zero and solve.
- Determine whether the second derivative is undefined for any x-values.
- Plot these numbers on a number line and test the regions with the second derivative.
