Answer:
closed circles on 1 and 4 with arrows pointing outward
Explanation:
We assume your graph is of ...
x ≤ 1 ∪ x ≥ 4
__
The inequality symbols include the "or equal to" case, so the circles at 1 and 4 will be closed.
x ≤ 1 means the arrow points left of x = 1.
x ≥ 4 means the arrow points right of x = 4.
The graph will have arrows pointing outward from the closed circles at x=1 and x=4.
___
If the graph is supposed to be that of
x ∩ x ≥ 4
then there will be no solution. No number can be both left of 1 and right of 4 on the number line.
