29. y = x5 - 5x4 - 240

130. y = x3 - 12x2

Step 1

Since you have submitted two questions, we'll answer the first question. For the second question please submit the question again and specify it.

To find inflection points we need second derivative.

Step 2

For point of inflection y"=0 from there find x.

At x=0 , it has multiplicity 2 so it is not point of inflection.

Only point of inflection is 3

Step 3

To find critical points we have to set y'=0 and sol...
