So this is okay for f to be a function but we'll see it might make it a little bit tricky for f to be invertible. Last updated at Jan. 28, 2020 by Teachoo. The term one-to-one correspondence should not be confused with the one-to-one function (i.e.) If R ⊆ A x B and (a, b) ∈ R, then we say that a is related to b by the relation R, written as aRb. Determine if a function is invertible Get 3 of 4 questions to level up! Let f be a function whose domain is the set X, and whose codomain is the set Y.Then f is invertible if there exists a function g with domain Y and image X, with the property: = ⇔ =.If f is invertible, then the function g is unique, which means that there is exactly one function g satisfying this property. (Hint: suppose g1 and g2 are two inverses of f. Then for all y ∈ Y, fog1(y) = IY(y) = fog2(y). Not all functions have inverses. Mathematics Notes for Class 12 chapter 1.
