"WebAnd a function maps from an element in our domain, to an element in our range. That's what a function does. Now the inverse of the function maps from that element in the range to the element in the domain. So that over there would be f inverse. If that's the direction of the function, that's the direction of f inverse. " - Can a quadratic have an inverse
