Determine the intervals on which the function is concave up or down and find the points of inflection. f(x) = 2x³ – 7x? + 8 (Give your answer as a comma-separated list of points in the form (* , *). Express numbers in exact form. Use symbolic notation and fractions where needed.) points of inflection: Determine the interval on which f is concave up. (Give your answer as an interval in the form (*, *). Use the symbol o for infinity, U for combining intervals, and an appropriate type of parenthesis "(",")", "["."]" depending on whether the interval is open or closed. Enter Ø if the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed.) x € Determine the interval on which f is concave down.
