Answer:
The set that indicates the graph will be (x I x ∈ R, x < 5).
Explanation:
There is a graph on the number line which has an open circle on 5 and a ray pointing left on the number line.
Therefore, the graph indicates the values of unknown x (say) on the number lent which are all real numbers less than 5 up to -∞ but not including the value 5.
Hence, the set that indicates the graph will be (x I x ∈ R, x < 5). (Answer)
