f(x)=(x+2)^34. The point (2, 4) is which of the following? A) An absolute maximum B) An absolute minimum C) A critical point but not an extremum D) Not a critical point E) None of these
I think the answer is C, am I right?

Best ResponseYou've already chosen the best response.0Yes. But I wonder if C is the right answer. Do you must find the maximum and the minimum for this problem? If so, what to do after finding the derivatives?

Best ResponseYou've already chosen the best response.1Okay, after you find the derivative, you set it equal to zero and solve for x.

Best ResponseYou've already chosen the best response.1You substitute a number smaller than and a number bigger than x into the derivative.

Best ResponseYou've already chosen the best response.1If the derivative changes from a  to a + the function has a local min. If the derivative changes from + to  the function has a local max.

Best ResponseYou've already chosen the best response.1A critical number is where the value of x you find makes the derivative equal to 0 or makes it undefined.
