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.
The outlined content above was added from outside of Formative.

Problem 3 Got It? Reasoning: Does -f(x) have the same zeros? Explain.
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 x-axis, so the zeros will stay the same.
Yes; -f(x) is f(x) reflected across the y-axis, so the zeros will stay the same.

Error Analysis: Your friend says that he has found a way to transform the graph of the function below to obtain three real roots. Using the graph of the function, explain why this is impossible.
You may use the embedded Desmos utility below to graph the function.
