To graph a rational function, identify the following seven characteristics:
- Domain: All x-values where the function is defined.
- Intercepts: Points where the graph crosses the x and y-axes.
- Vertical Asymptotes: Lines where the function grows without bound.
- Horizontal or Oblique Asymptotes: Lines the graph approaches as x increases.
- Holes: Points where the function is undefined due to common factors.
- Behavior Near Asymptotes: How the graph approaches asymptotes from both sides.
- Additional Features: Symmetry, increasing/decreasing intervals, and local extrema.
By analyzing these, you can understand the graph’s shape and key features without plotting points.

To analyze a rational function effectively, you want to identify key characteristics. First, determine the vertical asymptotes by finding values that make the denominator zero, as these often indicate where the graph will shoot to infinity. Next, find horizontal or oblique asymptotes, which give you a sense of the end behavior of the graph as
approaches infinity or negative infinity.
Then, check for any intercepts – both x-intercepts where the numerator is zero, and y-intercepts by substituting
into the function. Additionally, identify any holes in the graph that occur when there are common factors in the numerator and denominator. Lastly, examine the behavior near the asymptotes to understand how the graph approaches these lines, and summarize the overall domain and range based on the identified characteristics.
