$\"f%28x%29+=+sqrt%28+2x%29\"$
\n" ); document.write( " $\"f%282%29+=+sqrt%28+2%282%29%29+=+sqrt%284%29+=+2\"$
\n" ); document.write( " $\"f%288%29+=+sqrt%282%288%29%29+=+sqrt%2816%29+=+4\"$

\n" ); document.write( "So the function f includes the points (2, 2) and (8, 4). The average rate of change is simply the slope between these points:
\n" ); document.write( "avg. rate of change = $\"%284-2%29%2F%288-2%29+=+2%2F6+=+1%2F3\"$
\n" ); document.write( " \n" ); document.write( "
