- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.
"Determine the most suitable form of the expression representing the output of the function to display key features for: • a quadratic function."
"Make connections between a table, an algebraic representation, or a graph of a: • quadratic or exponential function that does not involve a transformation, not in context."

What you'll learn
- Choose the form of a quadratic function (standard, vertex, or factored) that displays the feature a question asks for, and produce that form by conversion
- Convert standard form to vertex form by completing the square (recalled from `sat-adv-equiv-ctsq`), including when the leading coefficient is not 1
- Convert standard form to factored form, read the zeros correctly from the factors, and recognize when no integer factored form exists
- Convert vertex form directly to factored form as a difference of two squares
- Expand vertex form or factored form back to standard form, and use the expansion to show that all three forms are the same function
