That makes sense because this is a continuous function. So the limit as we approach x equals zero should be the same as the value of the function at x equals zero. So this top, this is going to be four. And let's think about the limit of g of x as x approaches zero. So from the left, it looks like as x approaches zero, the value of the function is approaching zero. And as x approaches zero from the right, the value of the function is also approaching zero, which happens to also be g of zero. G of zero is also zero.
