    I think that you are a grate teacher in all the Things you teach it would be nice if i could be in one of your classes when it comes to math, because i half to re take the GED on the computer and the teacher said I should know about formulas so I would to know how does one remember all these things when it comes on a test when it comes to algerbra I would like to know Thank you

    @2:57 Wouldn't you have to find the derivative of (-4x) following the chain rule?

    How would you find the critical values for g(x)=x^2-8Inx

    When i solved, i got the critical points 0, 2 and -2.

    My closest guess would probs be is that he factored it

    By factoring, he's filtering the e out so you just get left with 1.

    I thought the critical points are when F(x)=0 and when f(0)= y, what about f(0) in this equation?
