Hello!
\n" ); document.write( "***
\n" ); document.write( "(f + g)(1) essentially means f(1) + g(1) -- plug 1 into both f and g, then add the results together.
\n" ); document.write( "***
\n" ); document.write( "First, let us find f(1):
\n" ); document.write( " $\"f%28x%29+=+x%5E2+%2B+1\"$
\n" ); document.write( " $\"f%281%29+=+1%5E2+%2B+1+=+1+%2B+1+=+2\"$
\n" ); document.write( "***
\n" ); document.write( "Now, find g(1):
\n" ); document.write( "g(x) = x - 4
\n" ); document.write( "g(1) = 1 - 4 = -3
\n" ); document.write( "***
\n" ); document.write( "Finally, add the results together:
\n" ); document.write( "f(1) + g(1) = 2 + (-3) = 2 - 3 = -1
\n" ); document.write( "***
\n" ); document.write( "Thus, (f + g)(1) = -1
\n" ); document.write( "Let me know if you have any questions! =) \n" ); document.write( "
