What is the domain and range of the absolute value parent function?

The domain of the absolute value parent function, ( f(x) = |x| ), is all real numbers, expressed as ( (-\infty, \infty) ). The range of the function is all non-negative real numbers, starting from zero, which can be expressed as ( [0, \infty) ). This means the function can take any real input and outputs values that are zero or greater.
