$\"f%28x%29=x-5\"$
\n" ); document.write( " $\"g%28x%29=x%5E2-2x\"$
\n" ); document.write( "First find f(-1).
\n" ); document.write( " $\"f%28x%29=x-5\"$
\n" ); document.write( " $\"f%28-1%29=-1-5\"$
\n" ); document.write( " $\"f%28-1%29=-6\"$
\n" ); document.write( "Then
\n" ); document.write( " $\"g%28x%29=x%5E2-2x\"$
\n" ); document.write( " $\"g%28f%28-1%29%29=g%28-6%29=%28-6%29%5E2-2%28-6%29\"$
