Question

Given the relation {(2, 3), (-2, 2), (1, 5), (0, -1)}, state the domain.

A. {-1, -2, 2, 3}

B. {-2, 0, 1, 2}

C. {-1, 0, 1, 2}

D. {-2, -1, 0, 3}

Answer 1

B is the correct answer. The domain is the set of x-coordinates within the function; it shows how far left or right the function on the x-axis.

The Domain of the function is {-2, 0, 1, 2}. These are the x-coordinates contained within the function. They are in numerical order. The first x-coordinate shows how far left the function is to the x-axis (-2) and the last right coordinate (2) shows how far right the function is to the x-axis.

So, your answer is B.

Answer 2

C.{-1,0,1,2}
