Question

What are the domain and range of f(x) = 2|x - 4|?

O domain: x < 2; range: (-∞, ∞)
O domain: (-∞, ∞); range: f(x) > 0
domain: (-∞, ∞); range: f(x) < 0
domain: x > 2; range: (-∞, ∞)

Answer 1

The domain and range of f(x) = 2|x - 4| is domain = (-∞, ∞),{x ∈ R} and range = {0, ∞ }, {y, y ≥ 0} respectively.
