Question

Which of the following is false?

Answer 1

a. f^-1(x) is a one-to-one function?
b. f^-1(x) has a domain of d < x < c
c. a = f^-1(f(a))
d. d/dx(f^-1(x))_>0
e. f^-1(c) = a

Answer 2

Assume that f −1(x) is defined by restricting f(x) to the domain a < x < b. Which of the following statements is false?

Answer 3

Opps, I meant f^-1(x).

Answer 4

i would go with A
the inverse of the function could not be a one-to-one function
