Question

if f^1(x)is the inverse of f(x) what is the value of f^-1(f(x))
a.x^-1
b.0
c.x
d.1

Answer 1

wait f^1 (x) is the inverse of f(x)
not f^-1(x)?

Answer 2

f(x) = x
The inverse is switching place of f(x) and x
x = f(x)
since x is the same, we can say that
inverse of f(x) = f(x)
so

f^-1 means inverse
inverse of f(x) = f(x) = x
