Integrated Math 3

Practice

Problem 1

Match each polynomial with its end behavior. Some end behavior options may not have a matching polynomial.

Practice

As gets larger and larger in either the positive or negative direction, gets larger and larger in the positive direction.
As gets larger and larger in the positive direction, gets larger and larger in the positive direction.

As gets larger and larger in the negative direction, gets larger and larger in the negative direction.
As gets larger and larger in the positive direction, gets larger and larger in the negative direction.

As gets larger and larger in the negative direction, gets larger and larger in the positive direction.
As gets larger and larger in either the positive or negative direction, gets larger and larger in the negative direction.

Problem 2

Which polynomial function gets larger and larger in the negative direction as gets larger and larger in the negative direction?

Problem 3

The graph of a polynomial function is shown. Which statement about the polynomial is true?

<p>polynomial function graphed. x intercepts = -2, -1, 1, 2. y intercept = 3 point 5. f of x increases as x increases in both the positive and negative direction.</p>

The degree of the polynomial is even.
The degree of the polynomial is odd.
The constant term of the polynomial is even.
The constant term of the polynomial is odd.

Problem 4

ForLesson 1: Let’s Make a Box

Andre wants to make an open-top box by cutting out corners of a 22-inch by 28-inch piece of poster board and then folding up the sides. The volume in cubic inches of the open-top box is a function of the side length , in inches, of the square cutouts.

Write an expression for .
What is the volume of the box when ?
What is a reasonable domain for in this context?

Problem 5

ForLesson 6: Different Forms

For each polynomial function, rewrite the polynomial in standard form. Then state its degree and constant term.
