Answer:
A. x ≥ 4
Explanation:
When circle closed we use ≥ to show an equal quantity stop
When circle closed at the lowest inequality we show a less than or equal to inequality ≤
When circle open we just apply the same > to show a larger quantity stop
when circle open we just apply the lowest inequality <
so < and ≤ is lowest numbers compared.
and > and ≥ is higher numbers compared.
