WebDEFINITION: right-hand limit: lim ⁡ x → a + f (x) = L \lim_{x \to a^+} f(x) = L lim x → a + f (x) = L We say "the limit of f(x), as x approaches a from the positive direction, equals L". It means that the value of f(x) becomes closer and closer to L as x approaches a from the right, but x is not equal to a. great falls financial advisors

WebDec 21, 2024 · We 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 1.4.1 and numerically in Table 1.4.1, 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. WebRemember that limits represent the tendency of a function, so limits do not exist if we cannot determine the tendency of the function to a single point.
