Answer:
The domain of the function is all real numbers less than or equal to 0.
Step-by-step explanation:
Domain of any function is the values x can take. The Range of any function is the values y can take.
In the given graph The graph is in second quadrant where x value is negative and y value is positive .Any point in this quadrant is of the form (-x,y) The graph is extended to left side showing x can take the values of all numbers less than or equal to 0.
Hence The domain of the function is all real numbers less than or equal to 0.
