Question

Problem 29c

Answer 1

Given information

Given:-

Step-by-step explanation

Step 1.

To find the inflection points and concavity we have to find the second derivative of the given function.

 

now set the second derivative equal to zero and by solving the equation, we get the result below.

 

if we find the LCD of the denominator of those values we will get  

whose LCM is 9. and has the factor of  

 

 so, the LCM for  is the numeric part 9 and should be multiplied by the part of the variable.

so, we will multiply each term by and by simplifying we get the terms below.
