document.write( "These problems become very easy once you get what the equation above is telling you. In that equation, the \"x\" in the parentheses is just a placeholder for whatever input you happen to provide to the function p. The rights side of the equation tells us what function p will do with its input (represented by the \"x\"): It will multiply the input by -6 and then subtract 10. Function p will do this <i>with every input</i>. It will multiply the input by -6 and subtract 10.<br><BR>\n" );
