Best ResponseYou've already chosen the best response.0ok....to find the zeroes you need to find the roots of the equation when f(x) = 0. So, set 2x^3  9x + 3 = 0. It is not obvious to me what the factors are in this case.

Best ResponseYou've already chosen the best response.0The three x values shown below are the "zeroes". Meaning the value of the function is zero for those values of x.

Best ResponseYou've already chosen the best response.0the zeroes of a function are where the y value is zero hence you set the function equal to zero. 0 = 2x^3  9x + 3. This function will not factor nicely so I would probably use a graphing calculator to find the zeroes.

Best ResponseYou've already chosen the best response.0oh so to find the zeros mean the xintercepts?

Best ResponseYou've already chosen the best response.0ok so am i allowed to use the graphing technology, or is there a way to do it without it?

Best ResponseYou've already chosen the best response.0hmmmm.......factoring that function is nearly impossible (at least for me). So....
