Answer:
{ x | 1, 2, 3, 4, 5, 6, 7, 8, 9 }
Step-by-step explanation:
We note that points between integer values have been excluded, so domain consists of integer x-values from 1 to 9, or
{ x | 1, 2, 3, 4, 5, 6, 7, 8, 9 }
and <em>not</em>
1 <= x <= 9
We know that
<span>If each window covering covers 15 windows, and there are a total of 50 windows to be covered,

the answer is
4 window coverings
