Use formal definitions of limits as x→ ± co to establish the limit. If f has the constant value f(x) = k, then lim f(x) = k. Complete the introductory statement. 0 be given. Find a number M such that for all x, x> M → k-k =

Limits

When it comes to calculus, limits are considered to be a very important topic of discussion. The main importance of limit lies in expressing the value of a function as it gets closer to a certain value. Also, limits can help you to understand other topics, such as continuity and differentiability better. In a broader sense, every calculus notion is a limit. Other branches of calculus have also been derived from limits.
