Rational Functions
Rational functions are functions that can be expressed as the quotient of two polynomials. They are also known as rational expressions or fractional functions. Rational functions are widely used in mathematics, science, and engineering to model a variety of real-world phenomena.
Examples of rational functions include:
- f(x) = (x + 1)/(x – 2)
- g(x) = (x^2 – 1)/(x + 3)
- h(x) = (2x + 3)/(x^2 – 4)
Rational functions have several important properties:
- They are continuous at all points except for the points where the denominator is zero.
- They have vertical asymptotes at the points where the denominator is zero.
- They have horizontal asymptotes at the points where the degree of the numerator is less than the degree of the denominator.
