Had to stop and think about this for a bit.
Increasing: the function is increasing where the derivative is positive: (1,6),(8,9)
Decreasing: the function is decreasing where the derivative is negative: (0,1),(6,8)
Local Max: Derivative=0, change from positive to negative (6)
Local Min: Derivative=0, change from negative to positive (1),(8)
Points 2,3,5 and 7 are inflection points (not included in this question)
