Given:
\n" ); document.write( " $\"f%28x%29+=+6x%2B5\"$ and $\"g%28x%29+=+x%5E2-1\"$ find $\"f%28g%28x%29%29\"$ Substitute $\"g%28x%29+=+x%5E2-1\"$ for the x in $\"f%28x%29+=+6x%2B5\"$
\n" ); document.write( " $\"f%28x%5E2-1%29+=+6%28x%5E2-1%29%2B5%29\"$ Simplify.
\n" ); document.write( " $\"f%28g%28x%29%29+=+6x%5E2-6%2B5\"$
\n" ); document.write( " $\"f%28g%28x%29%29+=+6x%5E2-1\"$ \n" ); document.write( "
