Given information
Given:-
local maximum and minimum values
critical points
increasing intervals
decreasing intervals
Step-by-step explanation
Step 1.
To find the concavity and the inflection points we will determine the second derivative test.
we have already found the first derivative in the part one
(by using differentiation rule)
the domain of the second derivative is
(domain of a polynomial function)
substitute
solving this equation for x we find the result below
