Now you pick numbers in between the interval and test them in the derivative. If the number is positive this means the function is increasing and if it's negative the function is decreasing. I picked 0 a number from the left. #f'(0)=4# This means from #(oo,1)# the function is increasing. Then I picked a number from the right which was 2. #f'(2)=-4#When determining the intervals in which the graph of a function increase or decrease, some books include the ends while others do not.
