Answer: Here is the explanation. also it it +3y not -3y
Step-by-step explanation:
x+y+4+2y+1=x+3y+5 because
2y+y=3y
so now you have x+3y+4+1
4+1=5
now you have: x+3y+5
if you do not understand, What i am trying to say is, you need to add all of the same things.

Answer:
The mean is the average of all numbers. To find the mean you add all numbers and divide by how many numbers you have (i.e. 1+2+3 =6. 6/3 =2. Mean is 2.) Median is the middle of the numbers. To find the median arrange the numbers from least to greatest, and the number in the middle is the median. For example, 1, 2, 3, 4, 5. In this 3 is the median because it is in the middle. The outlier is the number that is different from others. For example, 1, 2, 3, 4, 17. In this case 17 is the outlier because it is different and farther than the other numbers.
Step-by-step explanation:
Let us try A
If we put x = -3 , then y= 27-36+3+1=-5 , thus it us not the polynomial of given points
Now moving onto B
If x = -3, then y =-81-27+36-3-1=76
If x= -1 , then y=-1-1+4-1-1=0
If x =0, then y=-0-0+0-0-1=-1
If x =1, then y= -1+1+4+1-1=4
Thus it is also not the polynomial with given point.
Now onto c
x= -3 , y=81+27-36+3+1=76
x=0, y = 0+0+0+0+1=1
x= -1 , y = 1+1-4+1+1=0
x=1 , y= 1-1-4-1+1=-4
x=2, y=16-8-16-2+1=-9
Hence C is the polynomial of given points
