Answer:
Domain: [0,∞), x
Range: [0,∞), y ≥ 0
Explanation:
1. Find where the FUNCTION is DEFINED.
A function is a set of ordered pairs where each first element is paired with one, and only one, second element. No element in either pair is without a partner.
2. Find the DOMAIN: The set of all x-values that a function passes through. Also, it is the left coordinate in a coordinate pair.
3. The RANGE: the set of all y-values that a function passes through. Also, it is the right coordinate in a coordinate pair.
