So now let's try to answer our question. What is the limit as x approaches 3? Well, let's think about the limit as x approaches 3 from the negative direction, from values less than 3. So let's think about first the limit as x approaches 3 at the limit of f of x as x approaches 3 from the negative direction. And all this notation here, I wrote this negative as a superscript right after the 3 says. So let's think about the limit as we're approaching from the left. So in this case, if we start with values lower than 3, as we get closer and closer and closer, so say we start at 0, the f of x is equal to negative 1.
