Question

Write an inequality that represents the graph.

Answer 1

Answer:  $x \le 4$

Reason:

There's a closed circle at the endpoint 4, and shading to the left.

This describes all values that are 4 or smaller

So x = 4 or x < 4. In short we say $x \le 4$

If the endpoint was an open circle, then we'd say x < 4 instead.
