Below is the function f(x). 6- 4 3 2 1 -7-6-5-4-3-2-1 12 3 4 6 -1 пр * -5- -6 Over which interval of a values is f'> 0? ○ (3,∞) ○ [3,∞) 0(-0,3) 0 (-0,3] 0 (-00,00] Over which interval of a values is f'< 0? ○ (3,∞) ○ [3,∞) O(-∞,3) 0 (-0,3] 0 (-00,00] Over the interval (-∞, ∞), this function is concave up (f">0) concave down (f" < 0)

The figure is the graph of the derivative, f', of a function f on [-4,4]. A Determine the intervals on which f is increasing. (Use the symbol U for combining intervals, and an appropriate type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed.) f is increasing on Determine the intervals on which fis decreasing. (Use the symbol U for combining intervals, and an appropriate type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed.) f is decreasing on Determine the intervals on which f is concave down. (Use the symbol U for combining intervals, and an appropriate type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed.) f is concave down on Determine the intervals on which is concave up.
