Given f(x)= 2/x - 4 and g(x)= $\"sqrt%281-x%5E2%29\"$ determine:
\n" ); document.write( "a) f(x+h)−f(x) / h
\n" ); document.write( "Is it $\"f%28x%29+=+%282%2Fx%29+-+4\"$ ?
\n" ); document.write( "Or $\"f%28x%29+=+2%2F%28x+-+4%29\"$ ?
\n" ); document.write( "==================
\n" ); document.write( "(b)g(2−h)
\n" ); document.write( "---
\n" ); document.write( "g(x)= $\"sqrt%281-x%5E2%29\"$
\n" ); document.write( "Sub 2-h for x
\n" ); document.write( " $\"g%282-h%29+=+sqrt%281+-+%282-h%29%5E2%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
