Use the graphs of and below to determine the -values of all local minima, maxima, and points of inflection.


    Continuous curve, coming from upper left, turning at approximate point, (negative 0.75, comma negative 0.1), turning at the origin, turning at approximate point (0.75, comma negative 0.1), continuing up & right, with x intercepts of negative 1 & 1.

will be increasing where is positive, and vice versa.
will be concave up where has positive slopes, and vice versa.

Local max at ; changes from positive to negative.
Inflection points at ; changes slope.
Local min at changes from negative to positive.


    Continuous curve, coming from left at about y = 1, concave down, turning at the point (0, comma negative 1), continuing up & right, at about y = 1, still concave down.       

See the hint in part (a).
