What is the limit of f of x, or we could say the limit of the square root of x plus five plus two as x approaches negative one? Well, this expression is continuous, or this function is continuous at x equals negative one, so we can just evaluate it at x equals negative one. So this is going to be the square root of negative one plus five plus two. So this is four, square root, principle root of four is two. Two plus two is equal to four. So since the limit of f of x as x approaches negative one is four, the limit of g of x as x approaches negative one is also four. And if this little, this little, I guess you could say, leap that I just made right over here doesn't make sense to you, think about it visually.
