\n" ); document.write( "\n" ); document.write( "Find f(h(4))
\n" ); document.write( "~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "           A simplest and the most natural way to complete such assignment
\n" ); document.write( "           is to do things / calculations step by step, \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "           WITHOUT COMBINING THEM INTO ONE FORMULA.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Step 1.  First, calculate h(4) = 3 * |4 - 9| - 10 = 3*5 - 10 = 15-10 = 5.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Step 2.  Now calculate f(h(4)) simply substituting the found value 5 \r\n" );
document.write( "         instead of h(4) into the formula for f\r\n" );
document.write( "\r\n" );
document.write( "             f(h(4)) = f(5) = 5^2 - 3 = 25 - 3 = 22.    ANSWER\r\n" );
document.write( "

\r
\n" ); document.write( "\n" ); document.write( "Done and completed. // Done and completed. // Done and completed. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "--------------\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Making other way, as @MathLover1 does, is REALLY BAD WAY.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "She instructs you to derive complicated formula and then follow this complicated formula, while there is much more simple way.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Following the @MathLover1 methodology, you INEVITABLY will make many mistakes on the way,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "while making it step by step, as I instruct you, SIMPLIFIES you work and make it much more error-proof.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Again, in this assignment, NOBODY REQUIRES you to derive long formula for the composition.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is UNNECESSARY EXCESSIVE job, which will lead you to making mistakes.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This benefit was that I came and explained you how to do it in a right way and warned you do not follow her way . . . \r
