Introduction
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)andf(2) = 9, we can assume that
