What are the domain and range of the function y= 5 sqrt(x-2) ??
\n" ); document.write( "------------------
\n" ); document.write( "Domain:
\n" ); document.write( "If x-2 is negative y would be the square root of a negative
\n" ); document.write( "number; then y would not be a Real Number.
\n" ); document.write( "So x-2 must be >= 0
\n" ); document.write( "Solving for x: x must be >= 2
\n" ); document.write( "------------------------------
\n" ); document.write( "Domain: All Real Numbers >= 2
\n" ); document.write( "-------------------------------------
\n" ); document.write( "Range:
\n" ); document.write( "The square root is always >= 0
\n" ); document.write( "So the range is All Real Numbers >= 0.
\n" ); document.write( "======================================
