/sci/ pls help me I have no idea how to do any of this shit and my test is tomorrow. Can you post post some vids or something on what this is and how I do it.
critical values and points of inflection
intervals of concavity
intervals of increase

Critical points is the only part i understand, but wtf is concavity? And what is the chart at the side I don't understand that at all.
>>7799267
concavity-based on the sign of the 2nd derivative
the chart gives the sign of the derivatives of the function on different intervals of the domain(x-vals)
