Find each key feature of the function shown in the graph. enter all intervals using interval notation.
enter the x-intercepts as values of x only.

the graph with the x-coordinate marks -4, -2, 0, 2, and 4. the y-coordinate mark -4, -2, 0, 2, and 4. there is function which made up by joining the following points by line segments. the points are (-5, 0), (-3, 2), (0, -4), (2, 0), and (4, 1). it shows open circle point at (-3, 2) and (4, 1).
