📚 The video is about continuous functions in Calculus 1.

✅ To determine if a function is continuous at a certain point, calculate the limit of the function and compare it to the value of the function at that point.

❌ If the limit and the value of the function at a point are not equal, the function is not continuous at that point.

🔢 Calculating the limit of a function

📚 This video discusses continuous functions in Calculus 1.

🔢 Applying limits, the function approaches infinity when x approaches 0.

❌ In this specific case, the function is not continuous because the limit is not equal to the function value.

🎯 Understanding the properties of continuous functions is important in Calculus 1.
