Answer:
D
Explanation:
A filled in circle located on the number line indicates x can equal that value
If the circle is open then x cannot equal that value
An arrow pointing right from the circle indicates that x is greater
An arrow pointing left from the circle indicates that x is less
Since the number line has a filled in circle at x = 3 and the arrow is pointing to the right , thus
x ≥ 3 → D
