Using the graph given to us here, we want to find the specified limits or otherwise state that it does not exist. Now our first limit here is a left sided limit, the limit of f of x as x approaches 0 from the left. Now coming in from that left side approaching that value of 0, I see that my function is coming close to a value of 0 as well. Now from that right side, my right sided limit as x approaches 0 from the right, I see that again my function is kind of closing in and getting really close to this value of 0. Now since these two limits, my one-sided limits from the left and the right, are equal to each other, I already know what my limit of f of x as x approaches 0 is. It's that same value of 0. Now again here, reminder that it does not matter what the value of our function is at 0, just what our function is doing as x gets really, really close to 0. Thanks for watching, and I'll see you in the next one.
