Inflection Point Calculator

Inflection Point Calculator:

An inflection point calculator is an online tool that is used to find the inflection point of a given function. Inflection points are fundamental in understanding the behaviour of a function graph, especially where the concavity changes. 

The rate of change of slope from increasing to decreasing manner or vice versa is known as an inflection point. In other words, an inflection point happens when a curve changes from concave up (bent upwards) to concave down (bent downwards), or vice versa.

How to compute Inflection Point?

To figure out how to compute the inflection point, follow the below examples 

Example 1:

Let's take the function:

8x^3 + 5x^2 + 2

Step 1: To find inflection points first we compute the first derivative

f'(x) = 24x^2 + 10x

Step 2: In the next step find the second derivative

f''(x) = 48x + 10

Now put the second derivative equal to zero to find the inflection point:

48x + 10 = 0

48x = -10

x = -10/48

x = -5/24

Hence the function f(x) = 8x^3 + 5x^2 + 2 has inflection point x = -5/24.

Example 2:

Let's take the function:

2x^3 - 6x^2 + 8x - 2

Step 1: To find inflection points first we compute the first derivative

f'(x) = 6x^2 - 12x + 8

Step 2: In the next step find the second derivative

f''(x) = 12x - 12

Now put the second derivative equal to zero to find the inflection point:

12x - 12 = 0

12x = 12

x = 12/12

x = 1 

Hence the function f(x) = 2x^3 - 6x^2 + 8x - 2 has inflection point x = 1.

FAQs

Might the calculator at any point find inflection points for implicit functions?

Our calculator is perfect for explicit functions, where the function is characterized in terms of a single dependent variable. However, for implicit functions, you might have to utilize specific devices. 

For what reason could a function have no inflection point? 

A function might have no inflection points if its concavity doesn't change. For example, the graph of a quadratic function like f(x) = x^2 is always concave up, so it has no inflection points.
