D. The domain of the function is all real numbers less than or equal to 0.
Which statement is correct ?
The given function is f(x) = √(-x)
We know that, The set of all values of x is called domain & the set of all possible values of y is called range.
Here, the graph of the given function starts from origin (0, 0) and go along 2nd quadrant.
So, The function takes x = 0 & many other negative(only) values of x
Therefore, the domain of the function is all real numbers less than or equal to 0.
Also, the function takes y = 0 & many other positive(only) values of y.
Therefore, the range of the function is all real numbers greater than or equal to 0.
Hence, 4th statement is correct.
