Part of video series Rational Functions
Given a rational function which has common factors in both the numerator and denominator, determine the locations in the graph of the simplified expression where holes would be located.
- What are holes in the graphs of rational functions?
- When is a rational function undefined?
- Where is f(x) = (x^2 + x - 6)/(x - 2) undefined?
- How can you identify holes in the graph of a function?
This lesson explains the concept of holes in graphs of rational functions where the function is undefined. The graph of this function appears to be a straight line except there is a hole in one spot on the graph.
