Hello,
So they don't intersect !!!!!!!!!!!!!!!!!!!!!!!
The graph represents the line x = 3.
Since there is more than one y-value for the one x-value provided, this graph is not a function.
The range is infinite, as there are no limits shown on the graph, and the slope is undefined.
The domain is only 3, since the only x-value on the graph is 3.
Based on this information, the statements that are true will be:
C. This graph is not a function because the value x = 3 is assigned to more than one y-value.
E. The equation of this line is x = 3.
(Note that D says the graph <em>is a function</em>. The graph isn't a function, as there is more than one y-value for x = 3.)
Answer:
3
