Understanding Asymptotes and Graphing Functions

The video tutorial explains how to determine and graph asymptotes of a given function. It starts with identifying vertical asymptotes by checking for common factors in the numerator and denominator. The tutorial then discusses horizontal asymptotes using limits and introduces slant asymptotes when the numerator's degree is higher. A long division method is used to find the slant asymptote equation. Finally, the function is graphed by plotting points and considering the asymptotes.

What is the first step in determining vertical asymptotes?

• Evaluate the limit as x approaches infinity.

• Perform polynomial division.

• Find the zeros of the numerator.

• Check if the numerator and denominator have common factors.

What condition indicates that a function does not have a horizontal asymptote?

• The degree of the numerator is less than the degree of the denominator.

• The degree of the numerator is equal to the degree of the denominator.

• The degree of the numerator is greater than the degree of the denominator.

• The numerator and denominator have common factors.
