For this problem the information that
\n" ); document.write( ".
\n" ); document.write( "\"f%28x%29+=+-x+-5\"
\n" ); document.write( ".
\n" ); document.write( "is extra information that you don't even need.
\n" ); document.write( ".
\n" ); document.write( "You are given:
\n" ); document.write( ".
\n" ); document.write( "\"g%28x%29+=+2x+%2B+3\"
\n" ); document.write( ".
\n" ); document.write( "and you are only asked to find \"g%280%29\". All this is telling you to do is to go to the equation
\n" ); document.write( "for g(x) and in that equation substitute 0 for every x. Then you just simplify it.
\n" ); document.write( ".
\n" ); document.write( "so go to the equation for \"g%28x%29\":
\n" ); document.write( ".
\n" ); document.write( "\"g%28x%29+=+2x+%2B+3\"
\n" ); document.write( ".
\n" ); document.write( "Substitute 0 for every x in this equation and you have:
\n" ); document.write( ".
\n" ); document.write( "\"g%280%29+=+2%2A0+%2B+3\"
\n" ); document.write( ".
\n" ); document.write( "The multiplication of 2 times 0 results in zero, so the equation simplifies to:
\n" ); document.write( ".
\n" ); document.write( "\"g%280%29+=+%2B3\"
\n" ); document.write( ".
\n" ); document.write( "and that's the answer for \"g%280%29\" that you were asked to find.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand what the problem was asking you to do and to see how to do it.
