The type of graph for a rational function is hyperbola
The parent function of a rational function is f(x)=1x and the graph is a hyperbola . The domain and range is the set of all real numbers except 0 . An excluded value in a rational function, is any x -value that makes the function value y undefined.
A hyperbola is an open curve with two branches, the intersection of a plane with both the halves of a double cone. The plane need not be parallel to the axis of the cone; the hyperbola will be symmetrical in any case.
Therefore, Hyperbola is the type of graph for a rational function.
