Identify where the function f (x) = x3 5x2 + 10x + l is increasing, decreasing, concave up, and concave down. (Give your answer as an interval in the form (*,*). Use the symbol 00 for innity, U for combining intervals, and an appropriate type of parentheses "(",")", "[", or "]" depending on whether the interval is open or closed. Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if no such interval exists.) f is increasing on: f is decreasing on: f is concave up on: f is concave down on
