(cannot divide by 0)

Answer 6

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

Answer 7

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
