The graph of the inequality is in the image below.
How to graph the inequality?
Here we have the inequality:
x < 0
This means that x is smaller than zero. To graph this we need to do a numberline. On that numberline we start drawing a open circle at x = 0.
The open circle means that x = 0 is not a solution of the inequality.
Then, we draw an arrow that goes to the left of that circle, this is, because x must be smaller than zero. An example of the graph is shown below.
