Shown below are the graphs of two cubic polynomials, fx and gx. Both the polynomials have the zeroes -1, 0 and 1

Question Image

Anya said, " Both the graphs represent the same polynomial, fx=gx=x+1x-0x-1 as they have the same zeroes.

Pranit said," Both the graphs represent two different polynomial, fx=x+1x-0x-1 and gx=-x+1x-0x-1 and only two such polynomial exist that can have the zeroes -1, 0 and 1

Aadar said, " Both the graphs represent two different polynomial and infintely many such polynomials exist that have zeroes -1, 0 and 1.
