How many roots does the graph polynomial function have?

a. 2
b. 3
c. 4
d. 1

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
