If it's an Android device, go to the Google Play Store and search "Facebook".

I guess she deleted the Facebook icon only. Check with her if she really
Tap the [Uninstall] button, which is unlikely 'cause to Uninstall apps
the user has to open the "App manager" and Tap the app to
display the options: [Uninstal] ^ [ForceStop] heard that

Facebook is a default app: Can't not be uinstalled, just disabled
To return the FB icon to its original spot..open the app drawer
Locate the FB icon--Tap+Hold & drag it To desired screen
