Solution Steps

Step 1: Identify the Degree and Leading Coefficient

The degree of the polynomial is 5, and the leading coefficient is 2.

Step 2: Apply the End Behavior Rules

Given that the degree of the polynomial is odd, and the leading coefficient is positive, the end behavior of the graph of the polynomial function is that it falls to the left and rises to the right.

Final Answer:

The graph of the polynomial function with degree 5 and leading coefficient 2 falls to the left and rises to the right.

Step 1: Identify the Degree and Leading Coefficient

The degree of the polynomial is 4, and the leading coefficient is 5.

Step 2: Apply the End Behavior Rules

Given that the degree of the polynomial is even, and the leading coefficient is positive, the end behavior of the graph of the polynomial function is that it rises to the right and rises to the left.

Final Answer:

The graph of the polynomial function with degree 4 and leading coefficient 5 rises to the right and rises to the left.

Step 1: Identify the Degree and Leading Coefficient

The degree of the polynomial is 4, and the leading coefficient is -4.

Step 2: Apply the End Behavior Rules

Given that the degree of the polynomial is even, and the leading coefficient is negative, the end behavior of the graph of the polynomial function is that it falls to the right and falls to the left.

Final Answer:

The graph of the polynomial function with degree 4 and leading coefficient -4 falls to the right and falls to the left.
