Unit 1 Overview
Unit 1: Limits and Continuity provides the foundation for understanding the fundamental concepts of calculus. It introduces the concept of a limit, a key idea that allows us to describe the behavior of functions as their inputs approach specific values.
Continuity, another crucial concept, characterizes functions that are smooth and well-behaved over an interval or at a specific point. Together, limits and continuity are essential tools for analyzing and understanding the behavior of functions.
Limits
A limit describes the value that a function approaches as the input variable approaches a specific value or infinity. Formally, a limit is defined using epsilon-delta notation, which provides a precise way to describe the closeness of the function value to the limit value for any given tolerance.

Continuity, Unit 1 limits and continuity test answers
Continuity measures the smoothness of a function over an interval or at a specific point. A function is continuous if its graph can be drawn without lifting the pen. There are different types of discontinuities, including removable, jump, and infinite discontinuities.

Test for Continuity
The formal test for continuity provides a step-by-step procedure to determine if a function is continuous at a specific point or over an interval. The test involves checking the existence of the limit at the point and the equality of the limit to the function value at that point.

Question Bank: Unit 1 Limits And Continuity Test Answers
What is the epsilon-delta definition of a limit?
The epsilon-delta definition of a limit states that for any real number ε > 0, there exists a real number δ > 0 such that if 0< |x - a| < δ, then |f(x) - L| < ε.
What are the different types of discontinuities?
There are three main types of discontinuities: removable, jump, and infinite.
How can I determine if a function is continuous at a point?
To determine if a function is continuous at a point, you can use the formal test for continuity. This test involves checking three conditions: the function must be defined at the point, the limit of the function as x approaches the point must exist, and the limit must be equal to the value of the function at the point.
