what is domain range and asymptote?
An asymptote is a line that the graph of a function approaches, but never touches. ... If the degree of the polynomial in the numerator is less than that of the denominator, then the horizontal asymptote is the x -axis or y=0 . The function f(x)=ax,a≠0 has the same domain, range and asymptotes as f(x)=1x .
