Help me please and thanks

Keep in mind that the graph counts in twos.
The factored form of the polynomial deals with the zeros in the graph. Identify the zeros in the graph:
Zeros at:
x = -4, (-4,0)
x = 4, (4,0)
Both values must be inputted into the answer and result in an output of 0, so the answer will be C. (x+4)(x-4).
Proof:
x = 4:
x = -4

Answer:
Approximately 34 grams of the healthy food
Step-by-step explanation:
For know the minimum value to be eaten daily to provide the requirement of both vitamins, is necessary to calculate the minimum value for every vitamin, so:
- vitamin E: We are going to use the rule of three in which 1 gram have 7% of the minimum daily requirement, then how many grams are going to be be the 100% of the daily requirement:
1 gram --------------7%
X grams -----------100%
So, it is necessary approximately 15 grams of healthy food to complete th 100% of the minimum daily requirement of vitamin E.
- vitamin A: We are going to use the rule of three in which 1 gram have 3% of the minimum daily requirement, then how many grams are going to be be the 100% of the daily requirement:
1 gram --------------3%
X grams -----------100%
So, it is necessary approximately 34 grams of healthy food to complete th 100% of the minimum daily requirement of vitamin E.
Finally for satisfy with both minimum daily requirement, we need to eat at least 34 grams of healthy food, because it is the maximum between the two X values.
