Question

What is the limit of `f(x)=4` as `x` approaches 1?

Answer 1

`\lim_(x->1) 4 = 4`

Note that the function `f(x)=4` is a straight line where the function is equal to 4 no matter what `x` is so the limit is 4 no matter where it is.

The answer is correct. Although obvious, there is a limit law that you should use for your reasoning:

`lim_(x->a)c=c`
