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