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

The roots of an equation is determined at the point where its graph passes the x-axis. In other words, the roots of the function is/are its x-intercepts. From the data points, that would be (3,0). So, the answer is A.
