Describe the right-hand and the left-hand behavior of the graph of
$n ( x ) = - \frac { 8 } { 11 } \left( x ^ { 3 } - 4 x ^ { 2 } + x + 1 \right)$
A) Because the degree is odd and the leading coefficient is negative, the graph rises to the left and falls to the right.
B) Because the degree is odd and the leading coefficient is negative, the graph falls to the left and rises to the right.
C) Because the degree is odd and the leading coefficient is positive, the graph falls to the left and falls to the right.
D) Because the degree is odd and the leading coefficient is positive, the graph rises to the left and rises to the right.
E) Because the degree is even and the leading coefficient is negative, the graph rises to the left and falls to the right.

Quizplus · Accepted Answer

The polynomial has an odd degree (3) and a negative leading coefficient (-8/11), so the graph rises to the left and falls to the right.
