What's the domain and range?

Answer:
Domain is [-6, ∞)
Range [2, 7]
Step-by-step explanation:
[] Domain = x coordinate values
[] Range = y coordinate values
Domain
Our x values start at -6 and go on forever towards positive infinity. This can be written as [-6, ∞)
- What is the [ for? It means that there is a point there and not a ray
Range
Our y values start at 7 and end at 2. Since the ray is straight on the value of 2 and not going up or down, we can write this as [2, 7]
- What are the ['s for? It means that there is a point on both ends the value doesn't go up/down more than the value written
