So we have the graph of y equals f of x right over here, and we want to figure out three different limits. And like always, pause this video and see if you can figure it out on your own before we do it together. Alright, now first let's think about what's the limit of f of x as x approaches six. So as x, let me do this in a color you can see, as x approaches six from both sides, well as we approach six from the left-hand side, from values less than six, it looks like our f of x is approaching one, and as we approach x equals six from the right-hand side, it looks like our f of x is once again approaching one. And in order for this limit to exist, we need to be approaching the same value from both the left and the right-hand side. And so here, at least graphically, so you never are sure with the graph, but this is a pretty good estimate, it looks like we are approaching one. Right over there, let me do it in a darker color.
