\

The solution set is
.
Graph the solution set on a number line.
Note: A dot means that this point is included in the solution set.
\Check:
\To check, substitute three different values for v into the original inequality: 3, a number less than 3, and greater than 3.
\Let three values
are substitute in the original inequality,
