Question 14

Describe the right-hand and the left-hand behavior of the graph of

f(x)= 4x5thpwr - 7x3rdpwr - 13

Because the degree is odd and the leading coefficient is positive, the graph falls to the left and rises to the right.

Because the degree is odd and the leading coefficient is positive, the graph rises to the left and rises to the right.

Because the degree is odd and the leading coefficient is positive, the graph falls to the left and falls to the right.

Because the degree is odd and the leading coefficient is positive, the graph rises to the left and falls to the right.
