Study Notes
Asymptotes and Mathematical Functions
- Asymptotes are lines that a curve approaches as the distance from the origin increases.
Definition of Asymptotes
- An asymptote is a line that a curve approaches as the input (or x-value) increases or decreases without bound, but never actually reaches.
Types of Asymptotes
- Horizontal Asymptote: a horizontal line that a curve approaches as the input increases or decreases without bound.
- Vertical Asymptote: a vertical line that a curve approaches as the input approaches a specific value.
Finding the Equation of a Horizontal Asymote
- To find the equation of a horizontal asymptote, compare the highest degree terms of the numerator and denominator of a rational function.
- If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0.
- If the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is y = a/b, where a is the leading coefficient of the numerator and b is the leading coefficient of the denominator.
- If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.
Removable and Non-Removable Vertical Asymptotes
- A removable vertical asymptote occurs when a rational function has a factor that can be canceled out in the numerator and denominator, leaving a function with no vertical asymptote.
- A non-removable vertical asymptote occurs when a rational function has a factor that cannot be canceled out in the numerator and denominator, resulting in a vertical asymptote.
