Best ResponseYou've already chosen the best response.1when 2nd derivative at critical point is negative you have max when positive then you have minimum

Best ResponseYou've already chosen the best response.1the 2nd derivative is showing the change in the slope the slope is the 1st derivative

Best ResponseYou've already chosen the best response.0So if the question says Find the extreme values of the function and where they occur, i find f'(x) and f''(x)?

Best ResponseYou've already chosen the best response.0Okay i got you, so for that function i do f', by quotient rule, and then critical values, then f''?

Best ResponseYou've already chosen the best response.1x not = 1 or 1 for this because do not want to divide by 0
