volume buttons not working on Mac

Hey, My Mac book pro's volume, pause and skip buttons and brightness buttons do not appear to be doing anything. I press them and they do not do their intended purpose (they don't do anything). My hypothesis is that I turned them accidentally from volume etc. keys to F5, F6 etc. keys. I do not know how I did this however (did not go into settings). Anyone know what is going on?

MacBook Pro (Retina, 13-inch,Early 2015), macOS Sierra (10.12.5)
