Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

Im a bit baffled on this one.

I have been told to perform the following integration:

[tex]\int y dx[/tex] from -1 to 14. I have been given some values of x and the corresponding values of y.

I just have one question, the fact that it is y dx is throwing me off. The trapazoidal rule is: I = h* [f(x1)-f(x2)]/2. This is probably really simple and a dumb question, but I assume that f(x1) corresponds to the value of y that I have been given for x1?
