It is true that a rational function is a function whose equation contains a rational expression. This is used in various math classes.
Discuss how you can use the zeros of the numerator and the zeros of the denominator of a rational function to determine whether the graph lies below or above the x-axis in a specified interval?
That's the definition of a "rational function". You simply divide a polynomial by another polynomial. The result is called a "rational function".
