Question?

No you cannot.

So?

Read about the nature of the cursor. It can be on Insert or overwrite. If the cursor is full square and flashing, that mean the memory register for the input line is full and you cannot input anymore strokes.

You may be making a confusion between intercepts and intersections. Intercepts are crossing of the axes. Intersections are between two curves: You need to have two curves graphed. You choose the first curve by selecting it (Up or Down Key), and then the second one.

Complete with zeros.

To transfer the operating system to the handheld, connect your handheld and computer with a USB Connection Cable and use TI-Nspire™ Teacher Software with TI-SmartView™ or TI?Nspire CX Student Software (Windows® / Mac®).

From TI FAQs:

What troubleshooting can I try if the TI graphing calculator will not turn on?

For the TI-83 Plus Family, TI-84 Plus Family:
Caution: The resets described in these troubleshooting steps will cause a loss of applications, programs and data. If at all possible please create a backup using TI Connect™ first.

1. Try a new set of AAA batteries.
2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
3. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.
4. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
5. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

I have a doubt, when I choose to completely format the calculator it will clear your operating system, files saved on it, but the product key (ID protuto) will be deleted too?

Were you also clearing the financial memory with 2nd [CLR TVM], or just the storage memory? If you don't, it's going to keep using whatever value you last used for PMT.

The expression a function acts on (i.e. what is inside the function) is called its argument. The arguments of some functions such as y=ax, y=ax^2 can have any real value. However some functions have arguments that must be in a specified domain: they are restricted to some specified intervals. For example y=square root (x) can act on any positive value, but if you feed it a negative value it is out of the correct domain.
