\n" ); document.write( " $\"y=f%28x%29\"$ \r
\n" ); document.write( "\n" ); document.write( "recall: $\"y\"$ actually means $\"f%28x%29\"$ \r
\n" ); document.write( "\n" ); document.write( "I find it helps sometimes to think of a function as a machine, one where you give a number as input to the machine and receive a number as the output. The name of the function is $\"f\"$ , the input is $\"x\"$ , and the output is read \" $\"f\"$ of $\"x\"$ \". The output is $\"f%28x%29\"$ sometimes given an additional name $\"y\"$ by $\"y=f%28x%29\"$ .\r
\n" ); document.write( "\n" ); document.write( "The domain of the function $\"y=f%28x%29\"$ is the set of values of $\"x\"$ for which a corresponding value of $\"y\"$ exists.\r
\n" ); document.write( "\n" ); document.write( "The range of the function $\"y=f%28x%29\"$ is the set of values of $\"y\"$ which correspond to the values of $\"x\"$ in the domain. \n" ); document.write( "
