Question

Identify the inequality that matches the picture.

  1. x < 4    
  2. x > 4    
  3. x ≥ 4    
  4. x ≤ 5    

Hint:

We are given a graph. The inequality is plotted on the graph. We have to write the inequality in mathematical form. We will see the limits of the inequality to write the answer.

The correct answer is: x > 4


    The blue line on the graph represents the inequality. It starts at 4 and continues further.
    Let x denotes the values satisfying the inequality.
    So, the variable satisfying the inequality is greater than 4.
    Now, we have to check if the values also included 4. From the graph, at point 4 there is a open circle. So, 4 doesn’t satisfy the inequality. It’s not included in the given values.
    The variable x is greater than 4 is the inequality.
    Mathematical form: x > 4

    We have to be careful about the limits of the inequality to solve the question.
