Answers:
Domain is
which converts to the interval notation [-2, 10]
Range is
which converts to the interval notation [-3, 2]
Step-by-step explanation:
The domain is the set of allowed x inputs. The left-most point happens when x = -2. The right-most is when x = 10. We can select any x value between these two endpoints. We include each endpoint because of the closed filled in endpoints. This is how we arrive at the domain
and that condenses to the interval notation [-2, 10]. Use square brackets to include each endpoint.
The range is the set of possible y values or outputs. The lowest the function curve can go is y = -3, and the highest is when y = 2. Therefore the range is the set of y outputs such that
and that condenses to the interval notation [-3, 2]
