A rational function is written in the form: where N(x) and D(x) are polynomials and D(x) does not = 0.
What are vertical asymptotes?
What are horizontal asymptotes?
What are the vertical and horizontal asymptotes of the function above?
A hole in the graph happens when you are able to simplify a rational expression by crossing out common factors. The common factors that were crossed out will create a hole in the graph.
Where is the hole in the above function?
