Use the following function and it's first and second derivatives to find the intervals where the function is increasing and/or decreasing and the x-values only of any local extrema. Then find the intervals where the function is concave up and where it is concave down and the x-values only of any inflection points. Use Calculus Methods and show all work. f (x) = (2x - x2 )ex f' (x ) = (2 - x2)ex f" ( xx) = (2 -2x -x2)ex
