1. 3/21 Warm Up- Monday Clean Out Folders Leave only your flipchart in folder Put Reference Chart on table We will use Quadratic Notes and Graphing Quadratic Equation Worksheet today.

2. 3/21 Objective: I will be able to graph quadratic functions in standard form.

3. 3/21 Assignment Graphing Quadratics Worksheet Numbers 3-7

4. Quadratics

5. ax 2 + bx + c =0 Standard Form of Equation

6. the u-shaped curve a quadratic equation makes when graphed. Parabola

7. Types of Parabolas If ‘a’ is POSITIVE, the parabola will OPEN UPWARD If ‘a’ is NEGATIVE, the parabola will OPEN DOWNWARD

8. Axis of Symmetry The vertical line that divides the parabola into two equal parts. It is the x-value of quadratic equation. To find x-value use this formula:

9. Vertex The turning point of the parabola. Written as (x, y) To find vertex: use axis of symmetry formula to find x. plug x into equation to find y.

10. Types of Vertex Minimum: vertex is lowest point ‘a’ is positive Maximum: vertex is highest point ‘a’ is negative

11. I will transform quadratic parent function by shifting, stretching, or compressing. 3/22 Objective

12. 3/22 Vocabulary Review Parent Function Linear Equation: y = x f(x) = x

13. 3/22 Vocabulary Review Transformation of Linear Equation: y = mx + b f(x) = mx + b

14. 3/22 Vocabulary Parent Function Quadratic Equation: y = x 2 f(x) = x 2

15. 3/22 Vocabulary Shift: y = x 2 + c f(x) = x 2 + c moves up y-axis y = x 2 - c f(x) = x 2 – c moves down y-axis

16. 3/22 Vocabulary Vertical Stretch: y = ax 2 f(x) = ax 2 “a” greater than one makes parabola narrower

17. 3/22 Vocabulary Vertical Compression: y = ax 2 f(x) = ax 2 “a” less than one makes parabola wider

18. 3/22 Vocabulary Reflection: y = -x 2 f(x) = -x 2 “a” is negative parabola opens downward

19. Quadratic Transformations y = ax 2 + bx + c - value: makes parabola open downward (reflection) more than 1: absolute value more than one makes parabola narrower less than 1: absolute value less than one makes parabola wider - value: moves parabola down + value: moves parabola up

20. Quadratic Transformations y = ax 2 + bx + c - value: makes parabola open downward (reflection) more than 1: absolute value more than one makes parabola narrower less than 1: absolute value less than one makes parabola wider - value: moves parabola down + value: moves parabola up
