Have one ellipse on one side, label it x, have another and label it f(x)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in x {-1,2,3}\r
\n" ); document.write( "\n" ); document.write( "in f(x){4,5}\r
\n" ); document.write( "\n" ); document.write( "draw a line from -1 to 4\r
\n" ); document.write( "\n" ); document.write( "draw a line from 2 to 5\r
\n" ); document.write( "\n" ); document.write( "draw a line from 3 to 5\r
\n" ); document.write( "\n" ); document.write( "Is it a function? Yes.\r
\n" ); document.write( "\n" ); document.write( "It isn't one-to-one, due to more than one x value producing the same y-value. \r
\n" ); document.write( "\n" ); document.write( "It is a function. If it wasn't we'd have where more the same x value is producing multiple y-values.
\n" ); document.write( "
