Question

The table shows the coordinates of several points on the graph of a polynomial.



x y
-4 9
-3 1
-2 -5
-1 -7
0 4
1 2
2 5
3 0
4 -6



According to the table, which point is a root of this polynomial?

A. (3, 0)
B. (2, 5)
C. (-1, -7)
D. (0, -4)

Answer 1

it's A

Answer 2

Because if you score this polynomial P, you have P (x) = y and the root of a polynomial is defined by P (x) = 0 and the only point satisfying this condition in your table is A (3.0)

Answer 3

so it's clear???
