Intuitive Limits
Overview
A limit describes the value a function approaches as the input gets close to a point — not necessarily the value at that point.
Key Concepts
1
“lim_{x→a} f(x) = L” means f(x) gets close to L as x gets close to a
2
The limit can exist even if f(a) is undefined
3
Approaching from a table of values builds intuition
