And as long as we aren't equal to one, this thing is going to be equal, as long as x does not equal one, x minus one over x minus one is just going to be one. So this limit is going to be one. So that one worked out. Now let's think about the limit as x approaches one from the right-hand side. Of, once again, I could write g of x minus g of one, but g of one is just zero, so I'll just write g of x over x minus one. Well what's g of x now? Well it's x minus one squared.
