Question

Mark all statements that are true

Answer 1

The definition of a function is where each input has a single output, and since x=3 has more than one output A is correct (and B is not correct)

For C, since x=3 (where 3=y) accurately describes the graph, this is correct (also since it's an equation)

D is correct since the domain is the possibilities of the x values and 3 is the only one that can fulfill it

Answer 2

Answer:

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

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