Answer:
x ∈ (-3, -1)
Step-by-step explanation:
In the graph, the vertical axis represents the y-value, while the horizontal axis represents the x-value.
y < 0 (y smaller than zero) happens in the region where the graph is below the horizontal axis.
Only by looking at the graph, we can see that y < 0 (the graph is below the horizontal axis) for the values of x in the interval (-3, -1)
Then all the values of x such that y < 0 are:
x ∈ (-3, -1)
