Khan Academy: Linear Algebra: Invertibility Implies a Unique Solution to F(x)=y

Curated by ACT

Video first reviews what it means for a function to be invertible. Shows that if a function is invertible then there is a unique solution to f(x) = y. Also shows that if there is a unique solution to the equation f(x) = y for all y then the function is invertible. [22:41]
