Left = 2 - 4x - 5 and F(x) = f'(dt). Find the critical points of F and determine whether they are local minima or local maxima. Give your answer in the form of a comma-separated list. Express numbers in exact form. Use symbolic notation and fractions where needed.
Local minima:
Local maxima:
Find the point(s) of inflection of F. Give your answer in the form of a comma-separated list. Express numbers in exact form. Use symbolic notation and fractions where needed.
Point(s) of inflection:
Determine the intervals where F is concave up and down. Give your answer as an interval in the form. Use the symbol ∞ for infinity, U for combining intervals, and an appropriate type of parenthesis depending on whether the interval is open or closed. Enter ∅ if the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed.
