Answer:
Step-by-step explanation:
cross multiply
-6 * 12 = 2 + z
-72 = z + 2
z = -2-72 = -74
Given:
The function f represents the diver's distance from sea level over time, in seconds.

To find:
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
.
![Domain=(-9,-2]\cup (-2,1]\cup (1,7)](https://tex.z-dn.net/?f=Domain%3D%28-9%2C-2%5D%5Ccup%20%28-2%2C1%5D%5Ccup%20%281%2C7%29)

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