So I'm just gonna make a table and try out some values as we approach one as we approach one from the different sides. X, f of x, and I'll do the same thing over here. So we are going to have our x and have our f of x. And if we approach one from the right-hand side here, that'd be approaching one from above. So we could try 1.1. We could try 1.01. Now f of 1.1 is negative one over 1.1 minus one squared.
