Answer:

  C  {(-4, 2), (-2, 1), (2, 0), (4, 5)}

Step-by-step explanation:

The domain is the set of x-values for which the function is defined.

Choices

A) The relation is only defined for x=2. It is not a function, because x=2 maps to an infinite number of y-values.

B) The domain is an infinite number of x-values. The listed values are included in the domain, but they are not the entire domain.

C) The list of first-values in the ordered pairs is the domain of the function it matches the given domain.

D) The list of first-values in the ordered pairs is not the same as the given domain.
Answer: C(-4,2), (-2,1), (2,0), (4,5)
