Question

Mark all the Statements that are true:

A. This graph is a function because the value of x is the same for every value of y.

B. This graph is a function whose range is the set {3}.

C. This graph is not a function because the value x = 3 is assigned to more than one value.

D. This graph is a function whose domain is the set {3}.

E. The equation of this line is x = 3.

Please help me with this question.

Answer 1

C and E

Explanation:

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

Answer 2

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 is a function. The graph isn't a function, as there is more than one y-value for x = 3.)
