Answer by Edwin McCravy(8999)   (Show Source): You can put this solution on YOUR website!For what value(s) of y is this expression not defined? ``` We factor the denominator: We know that an expression is NOT defined for any value of the variable for which the denominator equals 0. Therefore we set the denominator equal to 0, like this We now use the zero-factor property. Setting the first factor = 0, Setting the second factor = 0, So the expression is not defined for the values 3 or -2. Edwin```
