Answer 1

Step-by-step explanation:

There are two common ways of describing or specifying the members of a set: roster notation and set builder notation.

Answer 2

The two methods for representing a set are the Set builder method and the Tabular method.

Explanation:

• The Set-builder method is a shortcut for writing sets, especially those with an infinite number of elements. It works with numbers of all kinds, including integers, real numbers, and natural numbers. Sets having an interval or an equation can also be expressed using this notation.
• $A={\{x\vert x\in N,5<x<10\}}$ and is read as "set $A$ is the set of all ‘$x$’ such that ‘is an element of” and denotes membership of an element in a set.
• Tabular methods are used to solve issues where the state and action spaces are small enough to represent approximate value functions with arrays and tables.
