The function translation / transformation rules:\r
\n" ); document.write( "\n" ); document.write( "\"f%28x%29+%2B+b\" shifts the function \"b\" units \"upward\"\r
\n" ); document.write( "\n" ); document.write( "\"f%28x%29+-b\" shifts the function \"b\" units \"downward\"\r
\n" ); document.write( "\n" ); document.write( "\"f%28x+%2B+b%29\" shifts the function \"b\" units to the \"left\"\r
\n" ); document.write( "\n" ); document.write( "\"f%28x-b%29\" shifts the function \"b+\"units to the \"right\"\r
\n" ); document.write( "\n" ); document.write( "\"-f%28x%29\" reflects the function in the \"x\"-axis (that is, \"upside-down\")\r
\n" ); document.write( "\n" ); document.write( "\"f%28-x%29\" reflects the function in the \"y\"-axis (that is, swapping the left and right sides).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, what transformations turn \"y+=+x%5E2\" into \"y=+-2%28x+-+1%29%5E2%2B+3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-2\": reflects the function in the \"x\"-axis (that is, \"upside-down\")\r
\n" ); document.write( "\n" ); document.write( "\"%28x-1%29\": shifts the function \"1\" unit to the \"right\"\r
\n" ); document.write( "\n" ); document.write( "+\"+3\": shifts the function \"3\" units \"upward\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
