Homework Help: Pre-Calculus

Posted by Lucy on Sunday, August 31, 2008 at 2:42pm.

Approximate the greatest real zero of the function g(x)= x^3-3x+1 to the nearest tenth.

I know that there is a zero between -2 and -1, and another between 0 and 1 but do not know how to find it to the nearest tenth. The only example shown in my book uses a calculator and mine does not have instructions for the same functions as the one in the book. I have checked for online calculators and cannot find one to do the calculations either.

Any help would be great as I have to get finished with math this week.

Thanks
