Answer
$x<0\ \ $ or $\ \ x\geq 3$
Work Step by Step
There are two intervals here
On the left is an interval containing all numbers less than 0
(but not equal to 0, as the empty circle excludes the endpoint 0).
On the right, we have all numbers greater or equal to 3
(note the solid circle indicating inclusion of the endpoint 3 )
A number x from this set can belong to either of the above intervals, so the set shown in the graph can be written using inequalities as
$x<0$ or $x\geq 3$.
