true.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x can be any real number.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f(x) will always be negative, so the range of f(x) is equal to all real numbers smaller than or equal to 0.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "regardless of what value you have for x, the absolute value of x will be greater than or equal to 0 and the negative of that will always be less than or equal to 0.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the domain is all real values of x (x can be positive or negative).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the range is all real values of x smaller than or equal to 0.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if x = 0, the absolute value of x = 0 and - the absolute value of 0 will be 0.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if x = -5, the absolute value of x will be 5 and minus that will be equal to -5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if x = 5, the absolute value of x will be 5 and minus that will be equal to -5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the absolute value sign surrounding x is part of the rules of the function and does not impact the domain.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the domain is the value of x only.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the absolute value sign is part of the rules of the equation that translate the domain into the range.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the minus sign is the other part of the rules of the equation that translate the domain into the range.\r
