you have this function? JFX she go to no sign of Lex. We asked the well, this function is wanted one. Um so one of the conditions of being wanted one is that is injected. These means that means that up there, No once x one. I'm next to such that if function takes the same value on, uh, points are different. So Oh, this is never true for a one door for any injured function. So, you know, two points before in a statement was never true for on injected question. If you have two points that are different Hey, Santa, um, X one is dependent mix too. Then the value of the function. If there is no try the body of the option was we even two? These numbers never happens. Multiple points that they're different and function things. Uh, this anybody there, the function is not injected. So foreign objective function. These never helps. You just did. But for dysfunction will. It's, uh, previous experience. She tell you always have Arrietty function, so all right, there you have two points or devotion. Thinks the same about you. Well, that should be a straight line. So here my question of many places, so dot point on that point, the defendant that point bad boys over to function Thanks on the same value to be told the same value for why bite this welcome or specific ing sound. Police say if she calls you so a sign of zero issue is one. But what if you take bye, You're zero is your to pie because I have to buy. It's also why so at this point? One. Oh, we're supposed to play no sign of supply. Does she go to one so well, this means that is not my inject. So, um because, uh, she was divine identify, and so we'll know he's not.
