Question

Do all functions have limits?

Answer 1

Explanation for correct answer:

One of the basic concepts of calculus is limits (limits of a function); it deals with the value of a function at a particular point called limit.

Limits are used to calculate the definite integral of the function. Not all functions contain limits.

Some functions do not have any limit as the variable tends to infinity.

For example, the function $f\left(x\right)=x\sin x$does not have limits.

So, all functions do not have limits.
