\n" ); document.write( " $\"Functions\"$ are another way of describing certain things mathematically. There is a special type of $\"algebraic+\"$ $\"relations+\"$ called a $\"Function\"$ . \r
\n" ); document.write( "\n" ); document.write( "An algebraic relation is a set of ordered pairs, like (2,4) (3,6) (4,8) (5, 10).\r
\n" ); document.write( "\n" ); document.write( "The domain is: 2, 3, 4, 5 (These are all the $\"x\"$ values of the ordered pair)\r
\n" ); document.write( "\n" ); document.write( "The range is: 4, 6, 8, 10 (These are all the $\"y\"$ values of the ordered pair)\r
\n" ); document.write( "\n" ); document.write( "The $\"domain\"$ contains the $\"independent\"$ $\"+variable\"$ and the $\"range\"$ contains the $\"dependent+\"$ $\"variable\"$ . This means that the value of the range depends on the domain.\r
\n" ); document.write( "\n" ); document.write( "Think about the vending machine: What comes out of the machine (range) depends on what you put in (domain). You can't put in a nickel and expect a chocolate bar to pop out!\r
\n" ); document.write( "\n" ); document.write( "So. in your case $\"a=%281%2F4%29f\"$ , this is a function where the $\"domain\"$ is all values of $\"f\"$ and the $\"range\"$ is all values of $\"a\"$ . The $\"f\"$ is the $\"independent\"$ $\"+variable\"$ and the $\"a\"$ is the $\"dependent+\"$ $\"variable\"$ .\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
