It is the exact wording of the question.

A true statement regarding the graph of y=inverse relation of f(x) is

(a) an x-intercept occurs at (1,0)

(b) a y-intercept occurs at (0,-1)

(c) The point (-2,3) becomes (3,-2)

(d) The graph of the inverse relation is a function

The book says that the correct answer is ONLY (b).

I know (d) is apparently wrong if y=x^2. But, other choices seem to make sense to me if y=inverse relation of f(x).

Can someone explain why (b) is correct? Thanks.
