\n" ); document.write( "For x close to 4, $\"-8%2Fsqrt%28x%29+=+-8%2F2+=+-4\"$ .

\n" ); document.write( "As x approaches 4 from the left, the value of $\"4%2F%28x-4%29\"$ goes to negative infinity, because the denominator is very small negative. But as x approaches 4 from the right, the value of $\"4%2F%28x-4%29\"$ goes to positive infinity, because the denominator is very small positive.

\n" ); document.write( "Since the limit of the expression is negative infinity as x approaches 4 from one side and positive infinity as x approaches 4 from the other side, the limit as x approaches 4 does not exist. \n" ); document.write( "
