Question

Which statement best describes the domain of the function represented in the graph?

0 ≤ x ≤ 9 or x is between 0 and 9, inclusive
2 ≤ x ≤ 14 or x is between 2 and 14, inclusive
1 ≤ x ≤ 9 or x is between 1 and 9, inclusive
1 ≤ x ≤ 14 or x is between 1 and 14, inclusive

If you can as well, write an explanation for me thank you!

Answer 1

1 ≤ x ≤ 9 or x is between 1 and 9, inclusive

because as you can see on the graph the line starts at X cordinate 1 and ends at 9. so we can say 1<x<9. then we are going to have to add an equall sign because the line includes 1 and 9. so it will be like this---1 ≤ x ≤ 9.

Answer 2

domain represents the x-values. the x-values start at 1 and end at 9. 1 is included and 9 is included (otherwise an open dot would be shown).

1 ≤ x ≤ 9
