Simpsons Rule - Finding The Input?

I'm having trouble with a certain type of simpsons rule question, here is one for example;

"Use Simpson's rule with 2 strips to estimate the area between $\displaystyle y = x^3 -1$, the y axis and x=1."

The problem I'm having is that I've always done these when I've been given a table of values, where the values to put into the equation have been given to me. This type of question has really confused me because how can I find the values to input into the equation :S

Can someone point me on the right track please?

Thanks
