A line x=a is called vertical asymptote of a function f(x) if the value of the function tends to infinity when x tends to a. A line g(x)=ax+b is called asymptote of a function f(x) if the value of f(x) tends to the value of g(x) when x tends to infinity. In this model you can modify parameters in hyperbola equation and obtain changes of its vertical and horizontal asymptotes.
