Answer:
The answer to your question is Domain -∞ < x < ∞ Range -2 ≤ x < ∞
Step-by-step explanation:
The Domain is the set of all possible values the independent variable can take (x).
The Range is the values the function takes when it is evaluated by the independent variable.
For this function the domain is (-∞, ∞) or as an inequality -∞ < x < ∞
The range is consider from the vertex [-2, ∞) or as an inequality
-2 ≤ x < ∞
