Help

Answer 1

Domain: (-3, 7)

General Formulas and Concepts:

Algebra I

• Domain is the set of x-values that can be inputted into function f(x)
• Interval Notation - [a, b] is inclusive, (a, b) is exclusive

Explanation:

According to the graph, our x-values span from -3 to 7. Since both are open dot, they are exclusive from the domain:

Interval Notation (-3, 7)

Inequality Notation -3 < x < 7
