x +8 (1 point) Find the coordinates of all extreme values (absolute and local) of f(x) = x2 + 16x + 65 Enter each extremum as an ordered pair, e.g., (2,3); if there is more than one extremum of a given type, enter a comma-separated list of ordered pairs. If there are no extrema of a given type, enter "none". Absolute maxima: Absolute minima: Relative maxima: Relative minima
