Identify the domain and range of the function graphed below.

Answer:
Domain: (-∞, 4]
Range: [0, ∞)
General Formulas and Concepts:
Algebra I
Step-by-step explanation:
According to the graph, we see the line's x-value span from negative infinity to 4. Since 4 is closed dot, it is inclusive in the domain:
(-∞, 4] or x ≤ 4
According to the graph, we see the line's y-value span from 0 to infinity. Since 0 is closed dot, it is inclusive in the range:
[0, ∞) or y ≥ 0
