Question is attached

The correct answer are A,B,D and E

A. (F^-1(f(x))=x
B. F(f^-1(x))=x
D. Domain of f^-1(x) is the range of f(x)
E. Range of f^-1(x) is the domain of f(x)

Explain

When f(x) and g(x) are inverse of each other

F(g(x)= x
And the domain of f(x) is the range of g(x)

F^-1(x) is the inverse of f(x )

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

F^-1(x) is the inverse

F(f-1(x))= x

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

F^-1(x) is the inverse Of f(x)

Then domain of f^-1 is the range of f(x)

The range of f^-1 is the domain of f(x)

than do 23.50 times 18 and then divide your answer by 100 than you will get x.
