: : : : : 12x^3-12x^2?
: : : : determine GCF (which is 12x2)
: : : : then use distributive property to factor
: : : : 12x2(x-1)
: : : : ...are you sure you're in calculus???
: : : There are 2 more problems with the homework that go along with what you did above.
: : : 3) When the domain is restricted to -2 <= x <= 2, what is the global maximum and global minimum value of f(x) over this domain? Name both the value of the function and the x coordinate where the extreme value occurs.
: : : 4) Using Xmin=-2 and Xmax=2 and appropriate values of Ymin and Ymax, sketch a useful graph of y=f(x). Be sure to label with both the x and y coordinates all local extrema, global extrema, and inflection points.
: : : THANK YOU! THIS IS DUE TOMORROW AND I DO NOT KNOW WHAT TO DO ON THESE LAST 2!!!
: : 1. Read T.Gracken's answer to your other question.
: : 2. Read section of your textbook about "curve sketching."
: : 3. TRY to do your homework & if you get stuck on some specific detail, explain what you tried & then ask about it. Don't expect us to do your homework for you. You won't learn anything from that.
: I just need to know how to get started on those problems, a head start. Thanks.
Did you even bother to read Mr. G's explanation under "find critical points"? It's all there. Nobody can do any more than that to get you started, other than do the whole damn thing for you.
