Best ResponseYou've already chosen the best response.0In your expression, the only thing that can cause an undefined value is division by zero. Therefore, if the denominator of the expression equals zero, you'd be dividing by zero, which is an undefined operation. In order to find which values of x would cause division by zero, set the denominator equal to zero, and solve that equation for x. Those values of x cause the expression to be undefined. (Hint: there may be more than one answer.)
