[-/1 Points] DETAILS MY NOTES Math 110 Course Resources - Curve Sketching Course Packet on critical points - Curve Sketching Course Packet on classifying critical points using the first derivative test Determine the x-coordinates of the relative extrema of the function g(x) = 3x5 - 20x3 + 49. Enter each answer as a comma-separated list of values. The order of the values does not matter. Enter DNE if g(x) does not have any relative maximum or minimum values, respectively. x-coordinates of the relative maxima - x-coordinates of the relative minimal= 20.
