Domain
The domain is the set of all the values of x that satisfies the rational function in the graph.
The graph has a vertical asymptote at x=5, this means that x is never equal to 5.
Therefore, the domain of the function is:
Range
The range is the set of all the values of y that satisfies the rational function in the graph.
The graph has a horizontal asymptote at y=0, this means that y is never equal to 0.
Therefore, the range of the function is:
