Question

What is the limit of `x^2`?

Answer 1

The limit depends on the value that `x` approaches.

Generally, to get the limit, substitute the value that `x` approaches and solve for the resulting value.

For example, if `x` approaches 0, we can say that its limit is `0^2 = 0`

However, this is not always true.
For example, the limit of `1/x` as `x` approaches 0 is undefined.
