The domain of this graph is all real numbers and the range for the graph is [-4,∞).
The image shows a graph of a function that is defined for all real numbers. This means that the domain of the function is all real numbers.
The range of the function is all real numbers greater than or equal to -4. This means that the function can output any value greater than or equal to -4.
In interval notation, the domain and range of the function can be written as:
domain: all real numbers
range: [-4, ∞)
