find (f o f^-1)(5)
Is that EXACTLY the way the problem is written?

anonymous · Answer

idek i have no idea how to solve this

wolf1728 · Answer

I have no idea either - that's why I'm hoping that the problem is worded totally different than
find (f o f^-1)(5)
If nothing else it should say find (f of^-1)(5)
"f of" instead of "f o f"
