You can put this solution on YOUR website!
f(g(-2))
\n" ); document.write( "First find g(-2).
\n" ); document.write( "\"g%28x%29=-1-2x\"
\n" ); document.write( "\"g%28-2%29=-1-2%28-2%29\"
\n" ); document.write( "\"g%28-2%29=-1%2B4\"
\n" ); document.write( "\"g%28-2%29=3\"
\n" ); document.write( "Now use this value.
\n" ); document.write( "\"f%28g%28-2%29%29=f%283%29\"
\n" ); document.write( "\"f%28x%29=2x-1\"
\n" ); document.write( "\"f%283%29=2%283%29-1\"
\n" ); document.write( "\"f%283%29=6-1\"
\n" ); document.write( "\"f%283%29=5\"
\n" ); document.write( "\"f%28g%28-2%29%29=5\"
