From the graph, we get that:
The domain is (-4,4).
The function has no zeros.
The function is positive in the interval (-4, 0].
The function is negative in the interval (0,4).
------------------------------------
The domain of a function is the set that contains all the possible input values. In a graph, it is the values of the x-axis, that is, the horizontal axis.
In this question, the values of x are in the interval of (-4,4) thus, the domain is (-4,4).
The zeros are the values of x for which y = 0, that is, the values of x where the function crosses the horizontal axis. In this question, the function does not cross the horizontal axis, thus, it has no zeros.
The function is positive when the graph is above the horizontal axis. In this question, it is in the interval (-4,0].
The function is negative when the graph is below the horizontal axis. In this question, it is in the interval (0,4).
