Use the maximum/minimum finder on a graphing calculator to determine the approximate location of all local extrema.
-$$f ( x ) = 0.1 x ^ { 5 } + 5 x ^ { 4 } - 8 x ^ { 3 } - 15 x ^ { 2 } - 6 x - 63$$
A) Approximate local maxima at -41.132 and -0.273; approximate local minima at -0.547 and 1.952
B) Approximate local maxima at -41.13 and -0.196; approximate local minima at -0.55 and 2.029
C) Approximate local maxima at -41.16 and -0.301; approximate local minima at -0.638 and 2.043
D) Approximate local maxima at -41.075 and -0.361; approximate local minima at -0.504 and 1.895
