Algebra 2 5-9 Transforming Polynomial Functions

4 (1 rating)

| 23 Questions

Note from the author:

A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Problem 3 Got It? Reasoning: Does -f(x) have the same zeros? Explain.

No; -f(x) is f(x) reflected across the x-axis, so the zeros will not stay the same.

Yes; -f(x) is f(x) reflected across the x-axis, so the zeros will stay the same.

No; -f(x) is f(x) reflected across the y-axis, so the zeros will not stay the same.

Yes; -f(x) is f(x) reflected across the y-axis, so the zeros will stay the same.
