This self-checking online assessment has 10 questions that will help students practice finding the zeroes and intercepts of polynomial functions. There are hints available on the screen, and there is an online scratchpad that students can use to work on the problems.
This informational material will explain how to find all zeroes of a polynomial equation, including complex solutions. It will also introduce the concept of imaginary solutions. There is a corresponding video available. Practice questions with a PDF answer key are provided.
The Fundamental Theorem of Algebra tells us that any polynomial of degree n has n roots. At first, this may seem like a very convenient theorem but wait, what about counterexamples!? The function f(x) = x2 + 1 clearly has no roots along the x-axis and we are told to believe that this function has 2. Does this mean that the Fundamental Theorem of Algebra is false?
In the interactive, students will:
