Broken LCD or bad battery?

Hello, I was given a note 9 that I plan to get repaired Friday. I wanted to know the extent of the damage it has suffered. Previous owner threw it and cracked the front screen back screen and knocked the flash out of it. The phone willnot turn on at all as far as I can tell. Would there be any indication that The phone can still turn on with a cracked LCD? Or is my battery damaged? When I plug it into the charger no lights or vibration is present and holding the power button does squat. Would prefer answers/further questions emailed to me at; D.maynard35@yahoo.com

Will check back here later for answers thanks I'm advance!
