Answer:

Domain is [-1, 3]

Range is [1, 2]

================================

Step-by-step explanation:

The domain is the set of allowed input values. It's the set of all possible x coordinates of the points shown.

The left-most point is when x = -1, while the right-most point is at x = 3.

We can say
-1 \le \text{x} \le 3 meaning x is between -1 and 3, including both endpoints.

That compound inequality translates to the interval notation [-1, 3]

Square brackets are used to include the endpoints.

-----------------

The range handles the set of possible y outputs.

The lowest we can go on the graph is y = 1, and the highest is y = 2

Therefore we arrive at
1 \le \text{y} \le 2 which translates to [1, 2]
