How to solve for limits at infinity

WebWe can extend this idea to limits at infinity. For example, consider the function f(x) = 2 + 1 x. As can be seen graphically in Figure 4.40 and numerically in Table 4.2, as the values of x get larger, the values of f(x) approach 2. We say the limit as x approaches ∞ of f(x) is 2 and write lim x → ∞f(x) = 2. Similarly, for x < 0, as the ... WebDec 20, 2024 · An indeterminate form indicates that one needs to do more work in order to compute the limit. That work may be algebraic (such as factoring and canceling) or it may require a tool such as the Squeeze Theorem. In a later section we will learn a technique called l'Hospital's Rule that provides another way to handle indeterminate forms.

WebLimits at infinity are used to describe the behavior of functions as the independent variable increases or decreases without bound. If a function approaches a numerical value L in either of these situations, write and f ( x) is said to have a horizontal asymptote at y = L. derek so hip hing https://scruplesandlooks.com

WebFor the first limit it'll have to depend on what the value of "a" is. If a is nonpositive, as you can see, the limit will be 0. And for the second limit, after applying L'hospitals' rule, I believe you will only have -e^x/2e^x that simplifies to -1/2, so e^x should go away.
