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).
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.
