To select the correct graph of the inequality \( x < 3 \), consider the following points:
- Number Line Representation: The inequality \( x < 3 \) indicates that the values of \( x \) are all less than 3.
- Open Circle: At the point \( x = 3 \), since 3 is not included in the inequality, you would use an open circle to indicate that it is not part of the solution set.
- Leftward Shading: The shading on the number line should extend to the left of the open circle to indicate all the values less than 3.
So, look for a graph that shows an open circle at 3, with a shaded line extending to the left of that point.
