Algebra 2 5-2 Complete Lesson: Polynomials, Linear Factors, and Zeros

Problem 1 Got It?

Problem 2 Got It? What are the zeros of the polynomial function? Select all that apply.

Problem 2 Got It? Sketch a graph of the polynomial function. Use a color other than black.Be sure to include relevant graph detail: label axes, indicate units and scale on both axes, and use arrows to represent end behavior, as appropriate.

Problem 2 Got It? Graph of the polynomial function. Zoom and pan you graph to establish an appropriate viewing window.You may edit your sketched graph in the previous item, if necessary.

Problem 3 Got It? Use the factors in the left column to group polynomial expressions that, when set equal to y, match each description in the right column.

Problem 3 Got It? Graph the quadratic function and cubic function you created in the previous item on the same plane. Zoom and pan your graph to establish an appropriate viewing window.

Problem 3 Got It? Reasoning: How are the graphs you created in the previous item different? How are they the same?

Problem 4 Got It?

Problem 5 Got It?

Problem 6 Got It? Technology: The design of a digital box camera maximizes the volume while keeping the sum of the dimensions at 4 in. If the length must be 1.5 times the height, what is the maximum volume of the camera?

Which is a polynomial function in standard form with zeros -1, 1, and 0?

Vocabulary: Write a polynomial function h in standard form that has 3 and -5 as zeros of multiplicity 2.

Error Analysis: Your friend says that to write a function that has zeros 3 and -1, you should multiply the two factors (x + 3) and (x - 1) to get the function below.Describe and correct your friend's error. If necessary, use ^2 notation to represent exponents.

Review Lesson 5-1: Match each polynomial equation on the left with its version in standard form on the right.

Review Lesson 5-1: Classify each polynomial equation on the right by both its degree AND number of terms.

Review Lesson 4-4: Drag and group the factors (left column) of each expression (right column). Not all factors will be used.

Review Lesson 4-7: Match the solutions on the left with the quadratic equation(s) they solve on the right.Not all solutions will be used.

Vocabulary Review: Which expression does NOT have x⁴ as a factor ?

Vocabulary Review: Which factor tree shows the prime factorization of 14x² ?

Use Your Vocabulary: Consider the diagram. Classify each turning point and intercept on the left by dragging it to the appropriate description on the right.

Use Your Vocabulary: Identify the sentence(s) that show the correct use of turning point.Select all that apply.

Notes: Take a clear picture or screenshot of your Cornell notes for this lesson. Upload it to the canvas. Zoom and pan as needed.For a refresher on the Cornell note-taking system, click here.
