    curve analysis question

    Determine the values of "c" such that has three critical points, and determine the character and location of each one.


    Sooo... I'll find the first derivative and equate it to 0 to find the critical points.




    , ,

    Now ...what exactly should I do? I don't have any solutions to this question :/.
