Limits

A limit describes the value that a function approaches as the input gets closer to a specific point. It helps us understand the behavior of a function near that point, whether the function equals that value there or not. Think of it like approaching a stop sign—your distance decreases as you get closer, but the limit is about where you’re headed, not necessarily where you’re exactly at. Limits are fundamental in calculus for analyzing and understanding how functions behave, change, or approach particular values even when they might not be exactly defined there.
