WebThe limit of f(x) as x approaches v can sometimes be found simply by substituting v for x. However, if this value is undefined, simplifying f(x) before substituting v may provide a limit. ... When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is ... WebJun 11, 2024 · To determine the limit, we can factor out an x^2. In other words, we divide each term by x^2. Now, all of the terms except the first terms have an x or x^2 in the denominator. Because of this, we can now plug in infinity. The limit of the terms with a variable in the denominator will be zero. We can assume this because as the number in a ...
