And so let's just try to evaluate this limit from the left and right-hand sides. And we could simplify it, we already know that g of one is zero, so that's just going to be zero. So we just need to find the limit as x approaches one of g of x over x minus one, or see if we can find a limit. So let's first think about the limit as we approach from the left-hand side of g of x over x minus, g of x over x minus one. Well as we approach from the left-hand side, g of x is that right over there. So we could write this, instead of writing g of x, we could write this as x minus one, x minus one over x minus one. And as long as we aren't equal to one, this thing is going to be equal, as long as x does not equal one, x minus one over x minus one is just going to be one.
