Domain testing generally includes DNS resolution and configuration of you domain name. It can also include the network performance of the DNS, WEB and other services attached to the domain.

For a more detailed description of domains and DNS see:

For an example of some of the domain testing techniques see:

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

Domain and range are concepts that many students have trouble with, so you are not alone!

Domain is the x values of the relation.

Range is the y values of the relation.

If you have trouble remembering which one is which , like I do, D comes before R, just like x comes before y;)

To determine if a relation is a function, there are several tests that you can use. For every x value, there can be one and only one y value. If there is more than one y value for any x value, it is not a function.

Another test is the vertical line test. If a vertical line only goes through one point on the line, it is a function. If it goes through two points on the line, it is not a function.

As an example, let's look at y = (x-3)^2 + 6.

This parabola is in the form, y=a(x-h)^2 + k, where a indicates a stretch or compression, and whether the parabola opens up or down. If a is positive, it opens up, and the y value of the vertex represents a minimum. If a is negative, it opens down, and the y value of the vertex is a maximum. The values h and k are the x and y values of the vertex.

In this case, a is one, so the parabola opens up, with a minimum value of 6.''

Now back to the domain and range.

Since we can use any value for x in the equation, for the domain, x is an element of real numbers, sometimes written (xER).

For the range, y can only be greater than or equal to the minimum. So the range is y is an element of all real numbers, such that y is greater or equal to 6, sometimes written (yER'y>=6). Sorry I couldn't find the greater than or equal to character;)

Good luck.

Sometimes domains are not available until they are removed and re-added to a machine. You can try logging in locally as an admin, remove it from the domain, verify you are on the network, reboot, and add it back to the domain. A local machine login circumvents the need for a cert to login, but does not give access to domain resources. This will allow you to work on the machine and test the NIC you are troubleshooting.

After looking in the manual, I read that

It takes as input the COUNT of successes in each sample (x1 and x2) and the COUNT of observations in each sample (n1 and n2). Thus your values of x1 and x2 must be integers (whole numbers).. Besides I duplicated your example taking x1=21, n1=43, x2=18, and n2=38 and I did not get the domain error.

I was able to draw the graph also.

You might want to check your values.

Can you ping your router?

If you can, log into it and see if you have any problems with it. If you have ADSL, you will see the status of the line as well as whether you are connected or not. You may have a diagnostic feature that will test the connection to your provider.

If you have lost DNS with your provider, you will not be able to ping using names, only by IP addresses.

if your solution comes out negative, it will say this because x^2 can never be negative. therefore, your answer is out of the domain of the function and will not register because it isnt a real solution

what function are you using?

Here is an asurd example of a piecewise function

Y1=11 for X less than 10

Y1=3 for X in the range [10, 20[

Y1=X+5 for X in the range [20, 30[

Y1=10 for X larger than 30

Here is the screen capture of the Y= editor window.

You have

Y1=11 for X less than 10

Y1=3 for X in the range [10, 20[

Y1=X+5 for X in the range [20, 30[

Y1=10 for X larger than 30

Here is the screen capture of the Y= editor window.

You have

- the definition of the function within a domain, enclosed in () followed by the domain enclosed in ()
- a + to introduce the second piece (definition) (domain)
- + a third piece (definition ) (domain)
- and so on.
- Use the [2nd][TEST] key sequence to access the relational operators, less than, greater than, etc.

This issue could be caused by a few things in your config. First things to look at is your networking (taken past the point of ensuring the addresses are proper, same subnet and so forth) - can you ping the DC and the DNS? If you can ping can you resolve with an nslookup? Are you using DHCP - is it running? Do you have an active firewall?

The suffix's at the end of your post are troubling - is this a copy and paste of the error message or was it keyed in? Do you have a copy of your DCDiag.txt?

Run some NETDIAG tests such as NETDIAG /d:domain and/or NETDIAG /fix which should provide you with more specific information that will pinpoint the issue (hopefully).

Hi,

I think for your subdomain test.xyz.com you need to assign ns1.xyz.com and ns2.xyz.com as vaild authorative name servers for the domain xyz.com. Make the DNS entries onto ns1.xyz.com and ns2.xyz.com for your subdomain test.xyz.com.

Most sure that this will solve your problem

Regards,

Mahesh Pandilwar.
