The graph of polynomial f(x) = cut x-axis at (-1,0), (1,0) and y axis at (0,2). then the sum of its roots is?

This question was asked in exam of VMC. My answer was 0(zero). Am i ri8 plzz explain....!

0 us definitely wrong because there exists another real because it is a cubic

*is

x^3-x is a cubic equation which has roots - 1, -1, 0. And the sum of its roots is 0. So it is possible to have zero as a root of equation.

does that cubic satisfy the point (0, 2) ?
