Answer:
- The graph of the function is attached below.
- The x-intercepts will be: (2, 0), (-2, 0)
- The y-intercept will be: (-20, 0)
Explanation:
Given the function
As we know that the x-intercept(s) can be obtained by setting the value y=0
so
switching sides
Add 20 to both sides
Dividing both sides by 5
so the x-intercepts will be: (2, 0), (-2, 0)
we also know that the y-intercept(s) can obtained by setting the value x=0
so
so the y-intercept will be: (-20, 0)
From the attached figure, all the intercepts are labeled.
Answer:
The correct answer to the following question will be Error-detection.
Explanation:
Error-detection: The detection of errors caused during the transmission from the transmitter to the receiver by damage and other noises, known as Error-detection. This error-detection has the ability to resolute if something went wrong and if any error occurs in the program.
There are mainly three types of error-detection, these types can be followed:
- Automatic Repeat Request (ARQ)
- Forward Error Correction
- Hybrid Schemes
There are two methods for error-detection, such as:
- Single parity check
- Two-dimensional parity check

When a user is created in Linux using the useradd command, the <em>immediate state</em> of the created account is locked.
- The useradd command can be invoked in other to create a new user account using the following command
sudo useradd fast_user
<em>#fast_user</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>name</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>account</em><em> </em><em>created</em><em> </em>
- At this point, the account has been created but it will be locked until the required login details are set. This can be achieved using the line ;
sudo passwd fast_user
Therefore, an account created using the useradd command is in a locked state.
