What is a horizontal asymptote?

Back

A horizontal asymptote is a horizontal line that the graph of a function approaches as the input (x) approaches positive or negative infinity.

What are vertical asymptotes?

Back

Vertical asymptotes are vertical lines that the graph of a function approaches as the input (x) approaches a certain value, typically where the function is undefined.

The vertical asymptotes are at x = 0 and x = -2.

What is the significance of the degree of a polynomial in determining asymptotes?

Back

The degree of the polynomial in the numerator and denominator helps determine the existence and location of horizontal and vertical asymptotes.

Back

There is no horizontal asymptote since the degree of the numerator (3) is greater than the degree of the denominator (2).

What happens to the graph of a rational function near its vertical asymptotes?

Back

The graph will approach the vertical asymptote but will never cross it, often going to positive or negative infinity.
