Answer:
I don't even know if what you typed is a actual question or not so I'm just gone guess it's....A or B?
Step-by-step explanation:
It seems that the four graphs are the same and they do not have a negative change rate in the interval 0 to 2 in the x-axis.
A negative change rate means that when x increases the value of the function (y) decreases; this is, the function is decreasing in the interval being estudied, which is the same that going downward.
So, you must look for in your graphs where the equation is going downward.
For example, in the graph attached, that happens in any interval from negative infitity to 1.5.
The vertex will help you to identify it.
Given that the graph goes downward from negative infinity to the vertex, any interval that includes that range will have negative change.
You must look for a parabola that opens upward and whose vertex is in x = 2.

Answer:
Products Repaired Frequency
DVD Player 7
TV 3
Radio 3
MP3 Player 5
Blu-ray Player 7
Total = 25
Step-by-step explanation:
Frequency distribution table represent the information of a data in a tabular form telling us about the items present in the sample and the number of times it occur.
Each item was picked from the list and written under 'Products repaired' then the number of times each item appeared is the frequency.
Answer:
The equation is : r + 2 = 7
Step-by-step explanation:
1+1+1+1+1+1+1 = r + 1 +1
7 = r + 2
R = 7-2
R = 5
