If you put four in it, ln of four, well, that's, sorry, ln of four minus one, so that's gonna be ln of, sorry, ln of four minus three is, actually, let me just draw a table here, I'm confusing you. So if I say x, and I say g of x, so at three, you're undefined. At four, this is ln of one, ln of one, which is equal to zero. So it's right over there. So g of x is gonna look something like, something like that. And so you can see, at three, you have this discontinuity there. It's not even defined to the left of three.
