How would I find the domain of y = root(x-3) - root(x+3) ?
\n" ); document.write( "And how would I write that?
\n" ); document.write( "---
\n" ); document.write( "Since the radicands must not be negative, x-3 must be >=0
\n" ); document.write( "Domain: All Real Numbers,x, where x >= 3.
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "What about the domain of y = (x^2 + 8x + 12)/4throot(x+5) ?
\n" ); document.write( "x+5 mult be > 0
\n" ); document.write( "Domain: All Real Numbers, x, where x > -5.
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "Or y = log(2x-12) ?
\n" ); document.write( "2x-12 must be > 0
\n" ); document.write( "Domain: All Real Numbers, x, where x > 6.
