Given information
The given information is
To find the intervals of concavity and the inflection points.
Step-by-step explanation
Step 1.
First calculate the second derivative of function.
Then set the second derivative equal to zero and solve it.
Check if the second derivative is undefined for any values of .
Plot the number on the number line and test the regions with the second derivative.
Plug the 3 values to obtain three inflection points.
