I don't know how to find the
\n" ); document.write( "domain and range of f(X)*g(x)
\n" ); document.write( "where f(x)= 4x^(2/3) and g(x)= 5x^(1/2)
\n" ); document.write( "----
\n" ); document.write( "Domain of f is all Real numbers
\n" ); document.write( "Range of f is all Real numbers >= 0 because of the squaring
\n" ); document.write( "---------------
\n" ); document.write( "Domain of g is all Real numbers >= 0 because of the (1/2) power
\n" ); document.write( "Range of g is all Real numbers >= 0 because of the (1/2) power
\n" ); document.write( "----
\n" ); document.write( "So:
\n" ); document.write( "Domain of f(x)*g(x) is all Real numbers >= 0
\n" ); document.write( "Range of f(x)*g(x) is all Real numbers >= 0
\n" ); document.write( "================================================
\n" ); document.write( "Try graphing f(x)*g(x) so you can see the Domain and the Range
