Explanation:

The domain of a function is how far along it goes the x axis. So, the domain of the function is (-4, 4), as it starts at -4 and stops at 4.

The zeros of a function are where you plug in x and get 0 for y. Looking at the graph, the only point where y is 0 is where x is also 0. So the zero of the function is (0, 0).

Looking at the function, the function is never increasing. You would call a part of a function increasing if that part had a postitive slope. Looking at the function, tt is either decreasing or constant. A function is decreasing if the slope of that part is negative, and it is constant if the line is horizontal. The points where it's decreasing is (-4, -3), (-1, 1), and (2, 4).
