Answer:
Step-by-step explanation:
It's called the swapping of domain and range. Even without solving for the inverse function just yet, I can easily identify its domain and range using the information from the graph of the original function: domain is x ≥ 2 and range is y ≥ 0.
3s+7=S+5
-7 -S
2s = -2
S= -1
