Here is a multiple-choice question. 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.
