ANSWER
The function that the given graph corresponds to is

EXPLANATION
The given graph in the attachment has x-intercepts at

These are the solutions of the polynomial function represented by the given graph.
We can write all these solutions as factors to obtain,

The product of all these factors gives us the function whose graph was drawn.
This implies that,

Therefore the correct answer is option C.
Okay, so when dealing with unit rates you want to see how much you have of your main measurement. In this case your main measurement is ounces. Since you have 16 and 32 you are going to divide your dollar amount by those and round to the nearest tenth.
Here are the equations that need to be used. Figure out the answers to them and round. This will give you your answer
3.98/16=
5.98/32=
solve this answer by using substitution. set the first equation to x=-y+4 then substitute -y+4 for x in the second equation.
2(-y+4) + 3y=0
-2y+8 + 3y=0
y+8=0
y=-8
now use -8 and solve for x
x+(-8)=4
x=12
L = X
w = X - 8
P = 52 cm
P = 2l + 2w
52 = 2(X) + 2(X - 8)
52 = 2x + 2x - 16
52 + 16 = 4x
68 = 4x
68/4 = 4x/4
17 = X.
The length of the rectangle is 17 cm.
W = X - 8
W = 17 - 8
W = 9 cm.
The width of the rectangle is 9 cm.
So, the time is the Y axis and the speed is the X axis graph the times and the speed and fill in the boxes with the time and speed.
