Why is f(x)=|x+3| why is domain and range all real numbers
~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

1.  Why f(x)=|x+3| has the domain all real  numbers ?

    f(x) = |x+3| has the domain "all real numbers" because it defined for all real numbers.


2.  Why f(x)=|x+3|  has the range all real  numbers ?

    It is INCORRECT.

    f(x)=|x+3|  has the range all real  NON-negative numbers .



Plot y = |x + 3|
