Answer:
The number of roots of the graph is 3
B is correct.
Step-by-step explanation:
We are given a graph of polynomial.
Graph start from negative infinity and end at positive infinity.
The degree of polynomial must be odd.
In graph, we can see it cuts at three points
(-6,0) (-2,0) (-1,0)
This graph has three x-intercept.
Number of x-intercept is equivalent to real roots of the polynomial.
This graph is cubic polynomial because it has three x-intercept.
Hence, The number of roots of the graph is 3
