Given,
The expression of the function A is,
[tex]f(x)=\sqrt[\placeholder{⬚}]{(-x)}[/tex]
The graph of the function B is,
Required
The domain of the function A and function B.
For the function A, if the value of x is positive real number or the number greater than 0, then the value of y will be imaginary number. Which can be neglected.
Hence, the domain of the function A is set of real numbers less than or equal to 0.
For function B, it is clearly seen from the graph that the function have the value of x as the set of all real number less than or equal to 0.
Hence, the domain of the both function is set of real numbers less than or equal to 0.
