<span>"3 ≤ x ≤ 7 or x is between 3 and 7, inclusive" The domain of a function is the range of values for which the function is defined. Since your function is a graph, look at the minimum and maximum values of X for that graph. The graph is a straight line connecting (3,2) to (7,12). So the legal values of X are every value between 3 and 7. And since the value 3 exactly is acceptable as well as the value 7 being acceptable, then the range is from 3 to 7 inclusive. Now look at the available answers and you'll see that "3 ≤ x ≤ 7 or x is between 3 and 7, inclusive" is one of the available choices and it's correct.</span>

Answer:

If the discs were measured to the nearest milimetre, it might be possible, that they are actually 1.64cm wide instead of only 1.64cm as shown.

Therefore the box would fill up much quicker and there will not be enough space.

Step-by-step explanation:

1.6cm * 16 discs = 25.6cm (would fit)

1.64cm * 16 discs = 26.24cm (would not fit)
