You can put this solution on YOUR website!
f(x)=2x + 1 and g(x)=2x(squared) + x
\n" ); document.write( "[f o g](2) plug g(x) into f(x)
\n" ); document.write( "f(x)=2x + 1
\n" ); document.write( "f(x)=2(2x^2 + x) + 1
\n" ); document.write( "f(x)=4x^2 + 2x + 1
\n" ); document.write( "f(2)=4(2^2) + 2(2) + 1
\n" ); document.write( "f(2)=16 + 4 + 1
\n" ); document.write( "f(2)=21
\n" ); document.write( "
\n" );
