ANSWER
[tex](1,4)[/tex]
[tex](- \infty ,-3)[/tex]
EXPLANATION
The x-values for which the graph is below the x-values below the x-axis is the interval on which the graph is negative.
We can see from the graph that, for
[tex]x < - 3[/tex]
the function is negative.
This can be rewritten as:
[tex] (- \infty ,-3)[/tex]
Also for
[tex]1 < x < 4[/tex]
the function is again negative.
This is also written as:
[tex] (1,4)[/tex]
