The correct statement for the domain.

Solution:

Domain is the set of input values for which the function is defined.

Here, x values are the input values and they represent time intervals on which the function is defined

Here, the possible intervals for x are $-9$ .

$Domain=(-9,-2]\cup (-2,1]\cup (1,7)$

$Domain=(-9,7)$

Therefore, the domain is the time interval (−9, 7). Hence the correct option is A.
