Answer:
B. -6 does not belong to the domain but belongs to the range of f(x).
Step-by-step explanation:
We have the function,
.
So, the domain of the function is obtained when
i.e. ![x\geq 7](https://tex.z-dn.net/?f=x%5Cgeq%207)
That is, the domain is {x | x≥ 7}.
Now as we have,
→
→
→
→
.
That is, ![f(x)\leq 1](https://tex.z-dn.net/?f=f%28x%29%5Cleq%201)
Thus, the range of the function f(x) is {y | y≤ 1}.
Thus, we can see that,
-6 does not belong to the domain but belongs to the range of f(x).
I would say Song 1 on the top could be NO, and Song 1 on the bottom could be ON, then Song 2 on the very top could be NO again, then on the bottom of the very top could OO, then on the bottom of that could be NN, and on he very bottom could be ON.
Hope this helps.
