a$.$ Find the open intervals on which the function shown in the graph is increasing and decreasing

b$.$ lountily the function's local and aboolds extreme values, if any, siming where they occur.

a$.$ On what open intervalis$),$ If any, is the function increasing? Select the corect choice below and fill in any answer boxes within your choice.
