Question

PLEASE HELP!!
If F^-1(x) is the inverse of F(x), which statements must be true?
Check all that apply:
a. the domain of F^-1(x) is the domain of F(x)
b. the domain of F^-1(x) is the range of F(x)
c. the range of F^-1(x) is the domain of F(x)
d. the range of F^-1(x )is the range of F(x)
e. F^-1 (F(x))= x
f. F(F^-1(x))=x

Answer 1

hella

Answer 2

domain of f(x)=range of f^-1(x)
range of f(x)=domain of f^-1(x)

Answer 3

f(f^-1(x))=x
