Does the solution set in the given graph lie to the left or right of the endpoint? What does the open circle indicate?
x> 1.5
Practice makes perfect
Before we can write an inequality for the given graph, we need to take note of the endpoint and the direction of the inequality.
First, we see that the circle at the endpoint is open. This means that the inequality is strict and 1.5 is not included in the solution set. Next, we observe that the solution set lies to the right of the endpoint. Using x to represent the solution set, we can say that any value of x is greater than 1.5.
x > 1.5
