2. Odd one out Can you give a reason for which one you think is the odd one out in each row? You need to give a reason for your answer. A: y = 2x + 2B: y = 3x - 4C: y = 2x 2 + 2

3. Quadratic Graphs You need to know how to plot graphs of quadratic equations

4. Quadratic Graphs Plot a graph of the equation ‘y = x 2 + 1 + 1 4 2 910149x2x2 310-2-3x 5102125 y

5. Quadratic Graphs Plot a graph of the equation ‘y = x 2 + 2x 1583003y 6420-2-4-62x 9410149x2x2 3210-2-3x

6. Quadratic Graphs Plot a graph of the equation ‘y = x 2 - x 62002612y 3210-2-3x 9410149x2x2 3210-2-3x

7. Quadratic Graphs Plot a graph of the equation ‘y = 3 – x 2 4 3 2 910149x2x2 3333333 310-2-3x

8. Summary We have looked at plotting graphs of quadratic equations They will always be a curve, either an ‘n’ or a ‘u’ shape
