A rational function is a type of function where you divide one polynomial by another. In simpler terms, it’s like having a fraction where both the top (numerator) and the bottom (denominator) are polynomials. An important thing to remember about rational functions is that you can't have a zero in the denominator, so you need to figure out which values are not allowed. When you graph a rational function, you'll look for vertical asymptotes (places where the graph shoots up or down because the function is undefined) and horizontal asymptotes (lines that the graph approaches but never quite reaches as you go far to the left or right). Working through Rational Functions Worksheets helps students understand these ideas and see how the functions behave on a graph.
