Find the critical point(s) of the function y = 0 - 2 cos (0) at 0 € [-3, -π]. (Give your answer in the form of a comma-separated list of values. Express numbers in exact form. Use symbolic notation ar fractions where needed. Enter DNE if the function has no critical points.) critical point(s): Determine the x-coordinates of the critical point(s) that correspond(s) to a local minimum or a local maximum. (Give your answer in the form of a comma-separated list. Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if the function has no local minimum or local maximum.) local minima: Resour local maxima: Find the intervals on which the function is increasing or decreasing. (Give your answer as an interval in the form (*, *). Use the symbol co for infinity, U for combining intervals, and an appropriate type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed. Enter Øif the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed.) DELL Question Source: Rogawski 4e 79°F Mostly cloudy
