So you're asking you, uh, these functions Functions is want one, 12121 So but what one means either there is no Carney. There is no two points eggs worm next to so is because the two points on it's one is different. Look, so so Well, this is, uh this is Sam buries Jerry. So no two different points get sent to the same us. It is a common situation with these. Thanks, Mom. 62 on the clubs for the same. So here your domain on your inch. Here they have the same. You should little mean I'm gruff, shall we? You know, so two different boys get mom to the same onto So this is injected until me is that, uh, it hits every point in the domain until, by definition, is gonna be on the bridge, So want the one is jerky anointed. So one. Let's go. You want to know why? And so well, these function there's something these farm. So you have Ah, I understand. Uh, I'm a line that is low. My three. This is their function. We're these, uh, this conventional means that buses, they or something leftist. So if you draw any line. We only eat cigarette once. But all these functions said this fighter property. I'm also you got that you're going to see it goes well, you can solve these equations. Why? Because then minus the X, it's uniquely so so then over that I'm seeing because only one solution. So this function, ese indeed, wantto so? Because so, the answer is it's 1 to 1, yes.
