Quadratics Day 1

Essential QuestionHow can I identify

parts of a quadratic function's graph? As measured by getting

80% on the homework.

Your notes for the next 3 days are in this book.

Arrange the pages in numerical

order, then fold in half.

HW Help: Quadratics Day 1No work = no credit = no kidding!! (Especially on the back page!)

#1­3. The domain of a quadratic (with arrows) is always all real numbers! The range depends on the concavity and the y­coordinate of the vertex. Concave up (minimum) will be ≥ and concave down (maximum) will be ≤#4­5. Once you find the vertex, the line/axis of symmetry is just x = the x­coordinate!#6­7. Find your a, b, and c values. Make sure your equation says y=! Then plug a & b into x = ­b/2a. Simplify if you can.#8. y=x2 is the quadratic parent function...which graph makes a "u"?#9 is not easy! Solve each equation for y=. Then name the a, b, and c values of each. Plug into the axis of symmetry equation to find which has x=­1/2. HINT: start from the bottom!#10. Don't pick any equation we haven't learned yet!!
