Answer:
Domain: (-∞, ∞)
Range: [1, ∞)
Explanation:
The domain of a graph is all inputs, or x-values, of the graph. Here, we see that the graph continues on forever in both directions, as given by the "NOTE" in your screenshot. This leads us to the answer of all real numbers. This can be written as:
(-∞, ∞)
The range of a graph is all the outputs, or y-values, of the graph. Here, we see that the graph continues on upwards forever from the point (-2, 1). This gives us an answer of everything greater than or equal to 1, which can be written as:
[1, ∞)
