Overview of asymptotes of a rational function, vertical horizontal and slant

The video tutorial covers the concept of asymptotes in rational functions, explaining vertical, horizontal, and slant asymptotes. It discusses how to determine each type based on the function's degree and coefficients, and provides rules for identifying them. The tutorial also touches on the properties of asymptotes and their behavior in graphs.

What is an asymptote in the context of rational functions?

• A line that the function approaches but never touches

• A point where the function is undefined

• A point where the function has a maximum value

• A line that the function crosses frequently

How do you determine the vertical asymptote of a rational function?

• By setting the numerator equal to zero

• By setting the denominator equal to zero

• By finding the highest degree term

• By calculating the limit at infinity

What happens when the degree of the numerator is greater than the degree of the denominator in a rational function?

• The horizontal asymptote is y = 0

• There is no horizontal asymptote

• The function has a vertical asymptote

• The horizontal asymptote is y = 1

When the degrees of the numerator and denominator are equal, how is the horizontal asymptote determined?

• By the ratio of the leading coefficients

• By the product of the coefficients

• By the difference of the coefficients

• By the sum of the coefficients

Under what condition does a slant asymptote occur?

• When the function has no vertical asymptote

• When the degree of the numerator is less than the degree of the denominator

• When the degree of the numerator is equal to the degree of the denominator

• When the degree of the numerator is one more than the degree of the denominator

How is the equation of a slant asymptote found?

• By using long division of the numerator by the denominator

• By setting the numerator equal to zero

• By using synthetic division

• By finding the limit at infinity

What is the result of dividing the numerator by the denominator in a rational function with a slant asymptote?

• The product of the two

• The sum of the two

• The remainder

• The quotient without the remainder
