Domain: [1, 6]

Range: [1, 7]

General Formulas and Concepts:

Alg I

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.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
