Find the domain and range of each function. Show me step by step please.
\n" ); document.write( "y=-sqrt(x+3)-1
\n" ); document.write( "----
\n" ); document.write( "Domain:
\n" ); document.write( "x+3 cannot be negative.
\n" ); document.write( "---
\n" ); document.write( "Solve: x+3>=0
\n" ); document.write( "x >= -3
\n" ); document.write( "That is the Domain.
\n" ); document.write( "===========================
\n" ); document.write( "Range:
\n" ); document.write( "sqrt(x+3) is always >= zero
\n" ); document.write( "--
\n" ); document.write( "So, -sqrt(x+3) is always <= 0
\n" ); document.write( "---
\n" ); document.write( "Therefore y <= -1
\n" ); document.write( "That is the Range.
\n" ); document.write( "=======================
