Linear-fractional function

Properties of linear-fractional functions

1. Scope



2. Multiple value



3. Parity, odd parity

A function is odd , so its graph is symmetric relative to the origin

4. The point of intersection with the axes

Because , the points of intersection with the coordinate axes no

5. Continuity and differentiability

A function is continuous at every point of its region of definition and is derived

6. The increase and decrease of

when a function is decreasing on each interval

when a function is increasing on each interval

7. The graph of the function

when
