If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
there is no graph... but most chance it's all real numbers
The answer depends on what the graph is of: the distribution function or the cumulative distribution function.
The "x values that work are the domain numbers like for y=x+1 would be any real number. But, y= sqrx x would have to be non-negative.
It means that the function is not defined for a part of the domain.
