The problem states:\r
\n" ); document.write( "\n" ); document.write( "Express y as a function of x. What is the domain?
\n" ); document.write( "a) log(base 2)xy = 3log(base 2)x
\n" ); document.write( "b) log(base 5)y = 2log(base 5)x+1 + log(base 5)x-1
\n" ); document.write( "b) log(base 3)y-3 = 1 + 2log(base 3) \r
\n" ); document.write( "\n" ); document.write( "First notice that each problem has the same log base on both sides of =\r
\n" ); document.write( "\n" ); document.write( "a) we can divide both sides of = by log(base 2) which gives us
\n" ); document.write( " xy = 3x and y = 3 (all rational numbers)\r
\n" ); document.write( "\n" ); document.write( "b) divide both sides of = by log(base 5) and we get
\n" ); document.write( " y = 2x+2 + x-1
\n" ); document.write( " y = x+1 (domain is all rational numbers)\r
\n" ); document.write( "\n" ); document.write( "c) divide both sides of = by log(base 3) and we get
\n" ); document.write( " y-3 = 1 + 2
\n" ); document.write( " y = 6 (domain is all rational numbers)\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
