Properties of linear-fractional functions
- Scope
- Multiple value
- Parity, odd parity
- The point of intersection with the axes
- Continuity and differentiability
- The increase and decrease of
- The graph of the function
A function is odd , so its graph is symmetric relative to the origin
Because , the points of intersection with the coordinate axes no
A function is continuous at every point of its region of definition and is derived
when a function is decreasing on each interval
when a function is increasing on each interval
when
