Answer:
Inequality:
Set Notation:
Interval:
Step-by-step explanation:
Given
The Attached Number Line
Solving (a): The Inequality
i. On the number line, we notice that a thick line starts at number 3 and points to the right
ii. Also, there is a closed circle on number 3.
(i) & (ii) indicates that
Solving (b): Set Notation
The set notation that indicates is
Solving (c): The interval notation
The inequality implies that x starts from 3 and moves towards +infinity
The means that 3 is inclusive of the inequality
Hence:
The interval notation is
