What is the domain and range of this graph?

D: (-∞, 0)U(0, -∞) R: (-∞, 0)U(0, -∞)

Rules for real numbers: Commutative Rules

x + y = y + x / x • y = y • x

Rules for real numbers: Associative Rules

(x + y) + z = x + (y+z) / (xy) z = x (yz)

Rules for real numbers: Inverse Rules

x + (-x) = 0 / x • 1/x = 1, for x ≠ 0
