Answer:
A. -1 ≤ x ≤ 3
General Formulas and Concepts:
Algebra I
- Domain is the set of x-values that can be inputted into function f(x)
Step-by-step explanation:
According to the graph, our x-values span from -1 to 3. Since both are closed dot, they are inclusive in the domain:
[-1, 3] or -1 ≤ x ≤ 3
