What is the x-intercept of y=square root x^2+9?
\n" ); document.write( "------
\n" ); document.write( "Let y = 0
\n" ); document.write( "Then sqrt(x^2+9) = 0
\n" ); document.write( "Then x^2+9 = 0
\n" ); document.write( "x^2 = -9
\n" ); document.write( "x = +-3i
\n" ); document.write( "-----
\n" ); document.write( "There is no x-intercept.
