We get g of four, which is this area, essentially minus this area, 4.5 minus eight is going to be, let's see, four minus eight is negative four, add a.5, that's negative 3.5. Now let's try to figure out what g of eight is. So g of eight. And if you couldn't figure it out the first time around, try to pause the video again, and now that we've figured out g of four, try to figure out what g of eight is.
