Determine the intervals on which f'(x) is positive and negative, assuming that given figure is the graph of f. Consider only the interval [0, 6]. A x 1 2 3 4 5 6 (Give your answers as intervals 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.) f'(x) is positive on f'(x) is negative on
