# Lesson Worksheet: Continuity at a Point Mathematics • 12th Grade

In this worksheet, we will practice checking the continuity of a function at a given point.

Q1:

Discuss the continuity of the function at , given

• AThe function is discontinuous at because is undefined.
• BThe function is continuous at .
• CThe function is discontinuous on .
• DThe function is discontinuous at because does not exist.
• EThe function is discontinuous at because .

Q2:

Given , if possible or necessary, define so that is continuous at .

• A will make continuous at .
• B is already continuous on .
• CThe function is already continuous at .
• D will make continuous at .
• EThe function cannot be made continuous at by defining as does not exist.

Q3:

Given , if possible or necessary, define so that is continuous at .

• AThe function is already continuous at .
• BNo value of will make continuous because does not exist.
• C makes continuous at .
• DThe function cannot be made continuous at because is undefined.
