Answer:
Domain: All Real Numbers (ℝ)
Range: y ≥ -4
Explanation:
Domain:
The area of the graph that is between points of x
Technically where the graph falls from left to right
Range:
The area of the graph that is between points of y
Technically where the graph falls from top to bottom
Domain: We can see that the graph will extend forever left and right, so the Domain is All Real Numbers ( ℝ )
Range: The graph never goes below the value -4, so the Range is y ≥ -4
