Do I find y' , then set it to 0 and solve for x? That is the min **<<<<<<< No. You determine the x-coordinate of the extremum, maximum or minimum.**

Do I find y'', then set it to 0 and solve for x? That is the max **<<<<<< No. With y'' = 0 you determine the point of inflection. You can distinguish the min and max using the x-coordinates of the extrema as argumant in y''**

I don't need anyone to do this...just explain how to go about it please.

Thanks.
