Best ResponseYou've already chosen the best response.2you will need the 1st and 2nd derivatives 1st derivative = 0 gives the stationary points 2nd derivative is used to determine the nature of the stationary points

Best ResponseYou've already chosen the best response.2it thats to difficult, just find a graphing package and graph the curve like geogebra http://www.geogebra.org/cms/

Best ResponseYou've already chosen the best response.0um can you just show me the steps or something....I have a textbook and the instructions aren't the issue its my ability to apply it to this problem

Best ResponseYou've already chosen the best response.2ok... here is the easiest solution, use the table of values below,..... dw:1352186589941:dw substitute each x value into the graph... the largest positive y value will be the relative maximum and the largest negative y value will be the relative minimum. when you have done that, you'll find ordered pairs that match your choices...
