I already did the first 2, so please only help me on the last 3..

ANSWER
[tex]\begin{gathered} \text{ASYMPTOTE: y = 0} \\ \text{DOMAIN: (-}\infty,\text{ }\infty) \\ \text{RANGE: }(0,\text{ }\infty) \end{gathered}[/tex]EXPLANATION
The asymptote of a graph is the line the graph approaches without actually touching.
The graph given has only one asymptote, and it is a horizontal asymptote.
It is at point:
ASYMPTOTE: y = 0
The domain of a graph is the set of all values of x in the graph.
The domain of the given graph is:
[tex]\text{DOMAIN: (-}\infty,\text{ }\infty)[/tex]The arrow shows that the graph keeps going till infinity.
The range of a graph is the set of all values of y in the graph.
The range of the given graph is:
[tex]\text{RANGE: (0, }\infty)[/tex]This is because the graph never touches 0 on the y axis and the arrow points upwards.
