$\"3-z%2Fz%2B1+%3E=+1\"$
\n" ); document.write( " $\"3-z%3E=z%2B1\"$
\n" ); document.write( " $\"2z%3C=-2\"$
\n" ); document.write( " $\"z%3C=-1\"$
\n" ); document.write( "However since when z=-1, the denominator goes to zero so we cannot allow that value.
\n" ); document.write( " $\"z%3C1\"$
\n" ); document.write( "or in interval notation ( $\"-infinity\"$ , $\"1\"$ ). \n" ); document.write( "
