FILL IN THE BLANKS: A) For a relation to be a FUNCTION, a B) For a relation to have an INVERSE that is a function, a than one point. C) For a relation to be one-to-one (it is both a function and has an inverse that is a function) it must pass which test(s)? line must not pass through more than one point. line must not pass through more D) When you graph a function and its inverse, they should be symmetric about the line:
