Which of the graphs above is the graph of the equation below?
y = 13 – 632 + 111 - 6 = (1 - 3)(1 – 2)(1 - 1)

Shown below

To solve this problem, we need to analyze the leading coefficient and the roots of the polynomial function:

Recall that a polynomial function can be represented by:

So the leading coefficient is . In our problem, this coefficient is

Since is odd and the leading coefficient , then the graph must falls to the left and rise to the right. Also, the roots are . So the only graph that matches this is the fourth one as indicated below.

b, i believe, but not sure.
