We have a number line as indicated in the figure above. From this figure we know that the x-values increase from left to right. So we need to write the solution that matches the previous graph. Taking a look on the graph we see that [tex]x[/tex] begins in -3 and closes in 8, that is, [tex]x[/tex] takes values from -3 to 8. In a mathematical language this is given by the following statement:
[tex]x \in [-3,8][/tex]
