Every mathematical function can be thought of as a set of ordered pairs, or an input value and an output value.
|
|
- Examples include $f(x) = x^2 + 2x + 1$, and $\{(1, 3), (2, 5), (4, 7)\}$.

**A limit describes how a function behaves *near* a point, rather than *at* that point.***
|
|
- As an example, given a well behaved function~ $f(x)$ and $f(2) = 9$, we can assume that
