Answer:
Let f be a function
a) f(n) = n²
b) f(n) = n/2
c) f(n) = 0
Explanation:
a) f(n) = n²
This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.
Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:
f(a) = f(b) ⇒ a² = b² ⇒ a = b
The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number. For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.
b) f(n) = n/2
The above function example is an onto function because every natural number, lets say n is a natural number that belongs to N, is the image of 2n. For example:
f(2n) = [2n/2] = n
The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:
When the value of n=1, then
n/2 = [1/2] = [0.5] = 1
When the value of n=2 then
n/2 = [2/2] = [1] = 1
c) f(n) = 0
The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image. The above function example is also not an onto function because every positive integer is not an image of any natural number.
Answer:
when make a task list you would not include commands that are for any specific language like C++
Explanation:
pseudocode should be universal. So when creating the task list, you would not include commands that are for any specific language like C++, java, C#, or perl. The point of pseudocode is to design a program that can be translated in to any language.
Answer:
Blockchain transactions allow users to control their data through private and public keys, allowing them to own it. Third-party intermediaries are not allowed to misuse and obtain data. If personal data are stored on the blockchain, owners of such data can control when and how a third party can access it.

Answer:
Software reuse is the technique through which updating the software system through the already defined components or assets of the software.This helps in increasing the productivity ,cost decrement , quality improvement etc.
But in actual case, the software reuse still persist high cost due to modification of inflexible designing of software .It also costs more than expected for the maintenance and training of software.
The security of the software is always at risk because of the usual and advanced hacking and attacking by the hackers even when the protect of software is high.Thus, these statements verify that the benefits of cost and security of software is not actually realized.
