Given:
\n" ); document.write( " $\"f%28x%29+=+%283x%5E2%2B11x-4%29%2F%284x-16%29\"$
\n" ); document.write( "Find: $\"f%28-4%29\"$ Substitute (-4) for x in the above function:
\n" ); document.write( " $\"f%28-4%29+=+%283%28-4%29%5E2%2B11%28-4%29-4%29%2F%284%28-4%29-16%29\"$ Simplify.
\n" ); document.write( " $\"f%28-4%29+=+%283%2816%29-44-4%29%2F%28-16-16%29\"$
\n" ); document.write( " $\"f%28-4%29+=+%2848-48%29%2F-32\"$
\n" ); document.write( " $\"f%28-4%29+=+0\"$ \n" ); document.write( "
