From the given graph of f(x) = √-x. The domain of the function is all real numbers less than or equal to 0.
If the domain of a function is specified as "all real numbers less than or equal to 0," it means that the function is defined only for values of the independent variable (usually denoted as 0.
x) that are less than or equal to 0.
The domain is x ≤ 0
Domain interval notation: (-∞, 0)
The range is f(x) ≥ 0
Range interval notation: (0, ∞)
The domain of the function is all real numbers less than or equal to 0.
