Use Simpson's Rule and all the data in the following table to estimate the value of the integral

2
S ydx
-4

S=integral sign

x -4 -3 -2 -1 0 1 2
y 0 -4 -8 -9 1 5 -7

the function provided doesn't even fit with the data in the table

wut the hell is this?!
 
Try reading the problem again. "The function provided doesn't even fit with the data in the table" isn't true- they don't give you a function except through the data.
You are asked to use Simpson's rule to integrate
\int_{-4}^2 f(x)dx
where f(x) is given by the table. I just substituted "f(x)" for "y" because I think you were mistaking it for "x".
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
