Question

Identify the correct option that represents the domain and range for the function f(x) = 1/( x 2  -4).?

Answer

Domain: (-∞, -2] U [2, ∞); Range: (-∞, -1) U (-1, 0) U (0, ∞)

Answer

Domain: (-∞, -2) U (-2, 2) U (2, ∞); Range: (-∞, -1) U (-1, 0) U (0, ∞)

Answer

Domain: (-∞, -2] U [2, ∞); Range: (-∞, 0) U (0, ∞)

Answer

Domain: (-∞, -2) U (-2, 2) U (2, ∞); Range: (-∞, 0) U (0, ∞)
