To solve this inequality using a calculator, we begin by pressing Y=. Then we write the inequality in the first row. Notice that we will use x as our variable, as this is the only variable we are allowed to write using the calculator.
To draw the inequality we press GRAPH.
We cannot see the graph, as the windows settings do not allow it. We have to extend it in the positive direction of the x-axis. We can do that by pressing WINDOW and then make 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 right of 12. Therefore, our answer is correct.
