So x is getting closer and closer to eight. So if x is seven, f of seven is here. If x is 7.5, f of 7.5 is here. So it looks like our value of f of x is getting closer and closer and closer to three. So it looks like the limit of f of x as x approaches eight from the negative side is equal to three. What about from the positive side? What about the limit of f of x as x approaches eight from the positive direction or from the right side?
