So on f of x, as x approaches zero, notice the function itself isn't defined there, but we see when we approach from the left, we are approaching, the function seems to be approaching the value of negative one right over here. And as we approach from the right, the function seems to be approaching the value of negative one. So the limit here, this limit here is negative one. As we approach from the left, we're approaching negative one. As we approach from the right, the value of the function seems to be approaching negative one. Now what about h of x? Well, h of x we have down here.
