-5
O A. -1 sxs3
B. X2-1
O C. x is all real numbers.
OD. -5 sxs 4

Answer 1

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)

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
