Plz help me with this

The minimum y-value is -7.
I'm only a few Brainliests away from ranking up, so one would be much appreciated.
Answer: A) -7
Step-by-step explanation:
The Asymptote is 1 so the range of the graph is from +1 to -1.
However, there is also a shift down of 6 units, so the range of the transformed graph is from (+1-6 = -5) to (-1-6 = -7).
Therefore, the maximum is -5 and the minimum is -7.
