document.write( "The function is defined this way  f(x) = \"3%2F%282x-4%29\",  correct ?\r\n" );

document.write( "\r\n" );
document.write( "    1)  Calculate  f(-1) = \"3%2F%282%2A%28-1%29-4%29\" = \"3%2F%28-2-4%29\" = \"3%2F%28-6%29\" = -0.5.\r\n" );

document.write( "        You get then the average rate of change = \"%28f%285%29-f%28-1%29%29%2F%285-%28-1%29%29\" = \"1%2F6\".    ANSWER\r\n" );
