What is the sign-preserving property of continuous functions?

Q: Determine where the function m(x) = x+1 (x-1)(x-4) is continuous. The function is continuous on…

A:

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.
