Do you have the zeros of the derivative?
anonymous
  • anonymous
They are 0, 2, and -2

  • anonymous
ok. If you take the 2nd derivative and plug them in it will tell you which ones are maximums and minimums. If the 2nd derivative is positive that's a minimum → dec to inc If it's negative there's a max at that point → inc to dec
