You executed the Transform Application and it is still loaded in memory taking over the graphing duties from the native OS. You must unload it from memory.
Press the APPS key. Scroll and find Transfrm, then press ENTER. In the new screen select 1:Uninstall and press Enter.
Go to your Y= function editor to type in up to 10 functions.

SOURCE: I am trying to help

The Transfrm application has been executed previously. It remains in RAM and takes over the graphing duties of the native OS. You must Uninstall Transfrm (that does not mean delete it, just unload it from memory).
To do so,

  1. press the [APPS] button.
  2. Use arrow Up or Down (Up is faster) to reach Transfm.
  3. Select it and press [ENTER].
  4. In the new screen, select the number to the left of the Uninstall option.
  5. Go to draw your graphs. You will be able to draw up to 10 graphs.

My sidebar on the right-hand side of Facebook disappeared,and I don't know how to retrieve.can you please help.

First of all, lucky you; that is where all the advertising appears. Generally, it disappears on me when I select my own page instead of home - ergo, try selecting "home" from the top menu bar and see if the right-hand content you expect reappears. From the home page you can also select the small triangle on the far right of the menu bar (blue colored on my systems) and scroll down to settings; what you can control is controlled from there.

Toolbar for firefox 9

Are you trying to display the menu bar (which contains dropdown menus for "File", "Edit" etc.) at the top of the browser window?

If that is not shown, click on the "Firefox" button (at upper left corner), then go to Options and select "Menu bar".

(Alternatively, you can click the "ALT" key, then go to: View > Toolbars and then select "Menu bar".)

That will display the menu bar.

You may later hide the menu bar (if you wish), by going to: View > Toolbars and de-select "Menu bar".

You tube videos start and stop

The videos need some time to buffer/load.

This is indicated by the pale red line that is usually in front of the play bar which is the darker red bar.

Pause the video for around a minute for the video to buffer.
Then push play button.

You may need to set the detail down to 240p to increase the speed at which it loads.

Can you tell me how to de-authorise a computer that is no longer working from the home sharing on itunes. please

If the computer doesnt work at all, and you are up to the 5 limit for authorizations you can reset them all at once, this will de-authorize ALL of your computers and you will have to re-authorize the ones you want. If you have NOT reached your 5 limit you have to contact Apple to have the de-authorize a machine. (De-authorizing all machines can only be done once per year).

To use the first method (de-authorize all) do the following :

  1. Click iTunes Store in the menu on the left side of iTunes.
  2. If you're not signed in to the store, click the Account button, then enter your account name and password.
  3. Click the Account button again (your ID appears on the button), enter your password, and then click View Account.
  4. In the Account Information window, click Deauthorize All.

IF your computer still turns on, you can de-authorize just that computer by doing the following:

  1. Open iTunes.
  2. Choose Store > Deauthorize Computer (In earlier versions of iTunes, access this option from the Advanced menu).
  3. Select "Deauthorize Computer for Apple Account" and enter your Apple ID and password

I do not have sound on my computer

1.Look in the lower right corner of your screen, does the speaker icon next to the date and time have a red circle with a line through it? If so, right click the speaker icon, open volume mixer, and click the speaker icon for device to un-mute the speakers2_bing.gif.

2.If using Windows Media Player (I am sure this applies to other media players too) please check below the video which is playing and locate the volume control slide bar. There should be a Speaker Icon next to the bar, make sure the red circle with a line through it is not on this icon either. If so, click it to un-mute your media player. Also, make sure the volume within your media player is turned up in this same place.

3.Finally, if all else fails, click the windows bubble (start menu) and right click on "Computer" or "My Computer" and click "Manage". Select "Device Manager" from the list on the left, and scroll down to "Sound, Video, and Game Controllers2_bing.gif". Expand that list, if you have any errors (Yellow Triangles, Red X's) there, you will need to reinstall drivers which can be obtained from the manufacturer's website.

TI-84 silver: Black arrow instead of line in function mode

I have answered this question multiple times. I have no idea why you calculator refuses to allow you to choose more graph styles. Maybe you should reset it by clearing the RAM.
Concerning the connected asymptotes.
In truth your function has one aymptote namely the straight line x=2 but your graph has two asymptotic branches, one tends towards -infinity, the other toward + infinity. That they seem connected is an illusion due to the finite resolution of the screen. This is made worse if you select a connected graph instead of a dotted one. I am enclosing a screen capture of the graph for the same function, drawn on a calculator with better resolution.


This clarification being given, it remains that you still have a problem since you cannot choose other styles. Do try to reset the RAM, and choose dotted graphs. If that does not work, maybe you should update the OS or reinstall it from
I hope it solves your problem. If it does not, do not blame me, and remember that I tried my best.

I have a Nikon D80 that I inherited about a year ago. Not exactly sure what I am doing but all has been fine until today. when I press the menu button to view pics, nothing happens. Am wondering if I have...

To view the pics on a D80, you do not click on the Menu button. Instead, you should click on the green button with a triangle shape pointing to the right. That is how you can review your pics.

To move between pics after clicking the button, press the left/right button or move your main dial clockwise/counter-clockwise

To close your preview session, just click on the same button with the triangle.
