Answer:
D. [tex]0\leq x\leq 7[/tex]
Step-by-step explanation:
The domain is represented by all the x-values, whereas the range is represented by all the y-values. Since this question asks for domain, it will be all the x-values possible for the given graph. They are {0, 1, 2, 3, 4, 5, 6, 7} which is mathematically written as [tex]0 \leq x\leq 7[/tex].
