Learn how to evaluate a limit at infinity

The video tutorial explains how to simplify fractions by dividing each term by the highest power in the denominator. It demonstrates rewriting expressions as variables approach negative infinity and simplifies them by evaluating limits. The tutorial concludes with a summary of the process, emphasizing that terms divided by variables tend to zero, simplifying the expression significantly.

Explain how the highest power in the denominator is used in the simplification process.

What is the process described for simplifying the expression as x approaches negative infinity?

What happens to the terms involving x as they are divided by the highest power?

Discuss the significance of the result '0 over 7 equals 0' in the context of the limit evaluation.

What conclusion can be drawn about the horizontal asymptote based on the evaluation discussed?
