Finding Domain, Range and Asymptotes of Rational Functions

The function y=|ax+b|y=|ax+b| is defined for all real numbers. So, the domain of the absolute value function is the set of all real numbers. The absolute value of a number always results in a non-negative value. Thus, the range of an absolute value function of the form y=|ax+b|y=|ax+b| is y∈R|y≥0y∈R|y≥0. The domain and range See more
