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. So g of x is x, h of g of x, h of g of x is equal to x, or you could have gone the other way around. You could have started with a, well you could have done it multiple different ways, but also g of h of x. I could have just swapped these letters here, the letters h and g are somewhat arbitrary. So you could have also said that g of h of x is equal to x.
