I have the x and the f(x) for a set of x. I don't know the function, actually. This is sufficient to integrate it?
The x value might span from 1 to no more than 50, usually around 10. While y is always negative and it's peak might pass -100.
What's the simplest approach?
x 0 1 2 3 4 5 6 7 8 9
y 0 -3 -5 -7 -5 -3 -2 -1 -1 0
May I ask the Python code com compute that?
