Question

What is the domain of the set of ordered pairs?

{(7,-3), (-4,2), (-1,0), (2,-4), (0,-6)}

A. {-6, -4, -3, 0, 2}
B. {-3, -2, -1, 0, 6, 8}
C. D: {All real numbers from -3 to 8}
D. {-4, -1, 0, 2, 7}

Answer 1

D. {-4, 1, 0, 2, 7}

Step-, by-step explanation:

For any order pairs (x, y), x is an element of a Domain and y is an element of a Range.

For {(7, -3); (-4, 2); (-1, 0); (2, -4); (0, -6)}

the set {7; -4, -1, 2, 0} is a Domain.
