Teacher set the exam 'guided question' very intelligently such that the student will not Cheating by using Sc Calculator xxxEX/570EX/991EX , one line to get the complete final answer ,without showing details of working ! Good teacher must know the Max capabiliy of the Sc Calculator to avoid Cheating in the Exam .But to exploit Sc Calculator for better usage and verification .

Do you teach KSSM form 4 add math in this channel?

If the domain of x is an inequality with equal signs then the end points of the the curve must have full circle dots showing that they are inclusive. But if the domain of x is an inequality without equal signs then the end points of the curve must have empty circle dots showing that they are not inclusive. So for this case the end points (-2,10) and (8,30) must show full circle dots.
