To apply the leading coefficient test on a function.
Answer to Problem 38RE
The graph rises to the left and falls to the right.
Explanation of Solution
Given information:
The given function is:
The degree of the polynomial is odd and the leading coefficient is negative, so the graph rises to the left and falls to the right.
