Question

Given: A = {(2, 3), (5, 1), (-3, -2), (0, 3)}
What is the domain of A?

1. {-3, 0, 2, 5}
2. {-3, -2, 0, 1, 2, 3, 5}
3. {-2, 1, 3}

Answer 1

domain is x-values only

so within your list of points, take the x-coordinate only (the first number in each set of parentheses), then list them all out
