Chapter Test
Use an alternative method to express each set.
a.
b.{x:x is a month in the year}
c.{y:y is a person in your math class and also more than 100 years old}
Expert Solution
To determine
a)
To express:
An alternative method of each set
Answer to Problem 1CT
Solution:
Explanation of Solution
Definition of sets and elements:
A collection of objects is called a set and the individual objects in this collection are called elements or members of the set. We can use uppercase letter to denote the set and the lowercase letter to denote the elements.
For example:
Where S is the set and a, b, c, d are the elements
Sets can be represented by using two methods. They are
i) listing method
ii) set-builder notation
Listing method:
The elements in the set can be written as a list where the elements are separated by the commas and enclosed within the brackets.
Set-builder notation:
A shorthand used to write sets, if all the elements of set have some common characteristics. It is also used to define a set with infinite number of elements.
For example:
We can represent a natural numbers using set-builder notation,
We can read the above expression as “
Given:
The given set is expressed in listing method.
So we can express that equation in the set-builder notation which is the alternative method.

Students have asked these similar questions
Let n = 7, let p = 23 and let S be the set of least positive residues mod p of the first (p-1)/2
multiple of n, i.e.
n mod p, 2n mod p, ...,
2
p-1
-n mod p.
Let T be the subset of S consisting of those residues which exceed p/2.
Find the set T, and hence compute the Legendre symbol (7|23).
The first 11 multiples of 7 reduced mod 23 are
7, 14, 21, 5, 12, 19, 3, 10, 17, 1, 8.
23
The set T is the subset of these residues exceeding
2°
So T = {12, 14, 17, 19, 21}.
By Gauss' lemma (Apostol Theorem 9.6),
(7|23) = (−1)|T| = (−1)5 = −1.

(d) A function j : A → C that is not bijective.arrow_forwardLet f:R->R be defined by f(x)=x^(3)+5.(a) Determine if f is injective. why?(b) Determine if f is surjective. why?(c) Based upon (a) and (b), is f bijective? why?arrow_forward
