Find the domain and range of:
\n" ); document.write( "f(x)=8+6*log base 9 (x-7)\r
\n" ); document.write( "\n" ); document.write( "-----
\n" ); document.write( "Domain:
\n" ); document.write( "x-7 must be positive:
\n" ); document.write( "Solve x-7 > 0
\n" ); document.write( "x > 7
\n" ); document.write( "Domain is all Real numbers greater than 7.
\n" ); document.write( "-------------
\n" ); document.write( "Range:
\n" ); document.write( "The function is asmptotic to x = 7 and ranges
\n" ); document.write( "from -inf to +inf.
\n" ); document.write( "Range is all Real Numbers.
