And once again, if I wanted it mathematically to be the exact same expression, I would say well, now this is going to be equal to one over the square root of x plus two for x does not equal four. But we can definitely see what this function is approaching if we just now substitute x equals four into this simplified expression. And so that's just gonna be one over, so if we just substitute, if we just substitute x equals four here, you get one over square root of four plus two, which is equal to 1 4th. And once again, you can feel pretty good that this is going to be your limit. We've gone back into the green zone. If you were to actually plot this original function, you would have a point discontinuity, you would have a gap at x equals four. But then when you do that simplification and factoring out that x minus, or canceling out that x minus four, that gap would disappear.
