What is an asymptote?

• A point where the graph intersects the x-axis.

• A line that the graph crosses.

• A line that the graph approaches but never touches.

How do asymptotes affect the domain of a rational function?

• They define the values that are excluded from the domain.

• They create holes in the domain.

• They do not affect the domain.

• They make the domain infinite.

How do asymptotes affect the range of a rational function?

• They make the range infinite.

• They define the values that are excluded from the range.

• They create holes in the range.

• They do not affect the range.
