Answer:
D. The equation of this line is x=3
E. This graph is not a function because the value x=3 is assigned to mre than one y-value.
Step-by-step explanation:
The range is all real numbers.
The domain of this graph is x=3, but it is not a function
The graph is a vertical line whose equation is x=3 because the graph passes through (3,y).
This graph cannot represent a function because it will not pass the vertical line test.
In other words, the x-value of 3 is assigned to more than one y-value.
Therefore the correct answers are:
Option D and E
