So h would do this. H would get us back to our original value. So that's what the function h would do. And so we could view this point right over here, we could view it as x, so that is x, but we could also view it as h of g of x. So we could also view this as h of g of x. And I did all of that so that we can really feel good about this idea. If someone tells you that g and h are inverse functions, that means that h of g of x is x.
