document.write( "f(x)= x2 - x + 5\r\n" );
document.write( "g(x)= 2x - 4\r\n" );
document.write( "g(-4) = -12    |g(x) = 2x-4  ⇒ g(-4) = 2*-4 - 4 = -12\r\n" );
document.write( "f(g(-4))  Substitute that -12 value for x in the f(x) function\r\n" );
document.write( "f(g(-4)) = (-12)^2 +12 + 5 = 161\r\n" );
