\n" ); document.write( "\n" ); document.write( "a. Let's deal with the range first. An item of jewelry cannot have less than zero percent gold and it cannot be more than 100 percent gold. Hence, a valid real-world range for this function is

.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then, solving for

using the extreme values of the range, we get a domain of
