So if we want to determine if a function is one toe one, we essentially need that. If we have to outputs that air the same, then the inputs are also the same. So if we kind of just look at the horizontal line test which essentially helps us determine this or not notice how, if we just pretty much take any line here at least kind of any line in the middle here we will have where this gets intersected three times. So this essentially fails the horizontal until line test, which implies not one toe one. And I guess if you want to be a little bit more exact, you could actually say Like where these values look like they're around. But since I just kind of sketch the graph really quickly, all we really need to say is that it fails the horizontal line test.
