x ≤ 4

x ≤ −4

x ≥ −4

All real numbers

Answer 1

@.Sam.

Answer 2

Since there's no restrictions and "x" can move from -infinity to infinity, so what do you think?

Answer 3

i honsetly dont know, thats why i posted it here... do you know?

Answer 4

Its all real numbers
To find domains, the graph looks like this,

The values of "x" continues to infinity, so it can be any "x"
