And then maybe down here, it is defined for all x values greater than or equal to four and it just goes right through negative six. So notice, all of these functions as x approaches five, they all have the limit defined and it's equal to negative six, but these functions all look very, very, very different. Now another thing to appreciate is, for a given function, let me delete these, oftentimes we're asked to find the limits as x approaches some type of an interesting value. So for example, x approaches five, five is interesting right over here because we have this point discontinuity. But you could take the limit on an infinite number of points for this function right over here. You could say the limit of g of x as x approaches, not x equals, as x approaches one. What would that be?
