Can anyone explain how to graph x < 3?
draw a dotted vertical line at x = 3
Shade in the region to the left of that boundary line.
I assumed you were on the x-y plane
If you are just on a number line, put an open circle at x=3, then draw in the line to the left of that with an arrow at its end point.
Thank you.
Certainly! To graph the inequality x < 3, you need to plot all the points that satisfy the inequality on a number line.
1. Draw a horizontal number line, labeling the points from left to right.
2. Mark the point 3 on the number line by making a small vertical line.
3. Shade the region to the left of 3 since x is less than 3. This indicates all the values of x that make the inequality true.
Please note that since the inequality is not inclusive of 3 (i.e., x is less than but not equal to 3), make sure to leave an open circle at 3.
Your graph should look something like this:

The open circle ■ represents the value 3, and the shaded region to the left indicates all the values of x that are less than 3.
