Answer:
The given table is
Quantity(x) Price(y)
1 2.00
2 3.50
3 5.00
4 6.50
5 8.00
6 9.00
It means the points on the graph are (1,2), (2,3.50), (3,5), (4,6.50), (5,8) and (6,9).
The graph 1 represents all the above mentioned point, therefore option 1 is correct.
According to the graph 2, at quantity 6 the price of flower is 12, which is not correct. Therefore option 2 is incorrect.
The quantity of flower is always a whole number. So the graph is defined on the whole numbers only. It means the graph is a scatter plot instead of a curve of a straight line.
Therefore the option 3 and 4 are incorrect.

Answer:
D is the answer
Step-by-step explanation: Explanation:
The domain is the set of
x
-values that can be used to draw the function so,
You are unable to get a square-root of a negative number therefore the value under the square root must be
≥
0
.
Therefore we need all of the
x
-values that result in the value of
4
−
x
being
≥
0
.
4
−
x
≥
0
4
≥
x
x
≤
4
So all
x
-values
≤
4
will work in the equation. Now we right this in terms of all real numbers:
The Domain of
x
is all the real numbers expect when
x
>
4
(This produces a negative under the square root)
