State the intervals of increase and decrease

In summary, "state the intervals of increase and decrease" refers to identifying the specific values or points on a graph or function where the output or y-value is increasing or decreasing. These intervals can be determined by looking at the slope of the graph or function, or by finding the critical points. It is important to state these intervals because it helps us understand the behavior of the function and has practical applications. There can be multiple intervals of increase or decrease, which can be represented on a graph using arrows or shading.

What is the meaning of your picture ? It is utterly useless and confusing to me !

I agree with your answer, but what about x=0 ?

sorry, that graph wasn't supposed to be there!
x=0 is an inflection point
