To solve this inequality using our calculator we press Y=, then proceed with writing it in the first row.
To draw the inequality, we press GRAPH.
We cannot properly see the graph as the windows settings do not allow it. We have to extend it in the negative direction of the x-axis. We can do that by pressing WINDOW and then making the necessary changes. Let's change Xmax from -10 to -20.
By pressing GRAPH again, we draw the inequality using the new window settings.
We can see from the graph that the solution set lies to the left of -9. Therefore, our answer is correct.
