Plz help very important question!!!!!

Answer 1

Answer:

Domain: [1, 6]

Range: [1, 7]

General Formulas and Concepts:

Alg I

• Domain is the set of x-values that can be inputted into function f(x).
• Range is the set of y-values that are outputted by function f(x).

Step-by-step explanation:

We can find our domain and range from looking from the graph.

Domain

Domain encompasses x-values. According to the graph, the x-values span from 1 to 6. Since both are closed dots, they are included in the domain:

[1, 6] or 1 ≤ x ≤ 6

Range

Range encompasses y-values. According to the graph, the y-values span from 1 to 7. Since both are closed dots, they are included in the range:

[1, 7] or 1 ≤ x ≤ 7

Easy way to remember this: for Domain, look only at the x-axis and for Range, look only for the y-axis.
