Find the nonlinear asymptotes of the function
\n" ); document.write( "f(x)= sqrt. sign x^2-4x-21
\n" ); document.write( "f(x) = sqrt(x^2-4x-21)
\n" ); document.write( "x^2-4x-21 = 0
\n" ); document.write( "(x-7)(x+3)=0
\n" ); document.write( "x = 7 or x = -3
\n" ); document.write( "These are vertical asymptotes
\n" ); document.write( "=======================
