    Square root of a negative number is undefined.

    \[x+2<0\] \[x <-2\] Any value that is less than -2 will not be defined under the set of real numbers.

    x+2<=0 (cannot divide by 0)

    What are you talking about, that is incorrect. I know it cannot divide by 0, so it is just less than @MrNood

    I think you will find it IS correct. It asks if there are values of x for which the expression is not defined x=-2 results in an undefined expression x<=-2 is the correct range of values for which it is undefined
