Finding Zeros of Quadratic Functions: The Power of Factored Form

This lesson explains the importance of the factored form of quadratic functions in identifying zeros. It reviews linear and quadratic forms, highlighting how different forms help find key features like Y intercepts and vertices. The lesson emphasizes that zeros are values of X for which F(X) = 0, and factored form makes it easy to identify these zeros. Through examples, the lesson demonstrates how to verify zeros using substitution. The lesson concludes by reinforcing the utility of factored form in analyzing quadratic functions.

Explain how the Y intercept can be identified in different forms of quadratic functions.
