a)Determine the concavity and points of inflection.
b) Find the local max and local min points.
Can someone check my work?
f'(x)= undefined when x=0
f''(x)=undefined when x=0
therefore point of inflection occurs at (0,8) and there is no concavity, no local max and min points.
Question: for this particular case, a vertical tangent, there is no concavity correct??
