So it is a continuous function. So it takes on every value, as we can see, it definitely does that. It takes on every value between three and six. It might take on other values, but we know for sure it has to take on every value between three and six. And so if we think about four, four is right over here. The way I drew it, it actually looks like it's almost taking on that value right at the Y axis. I forgot to label my X axis here.
