Explanation:

Step1: Identify the starting point and type of endpoint

The graph has an open circle at 3, so 3 is not included. The arrow points to the right, meaning values greater than 3.

Step2: Write in interval notation

For values greater than 3 (not including 3), the interval notation is $(3, \infty)$.

Answer:

$(3, \infty)$
