Question

Determining the domain and range from a graph

Answer 1

Answer:

• Domain = (-∞, ∞)
• Range = [-2, ∞)

Explanation:

• There are no restrictions are the domain; it can be any real number.
• There are no y-values less than -2, meaning the range of y-values must all be greater than or equal to -2, since -2 is the minimum value.
