### QUESTION 1 of 10

Before plotting the graph of a quadratic equation, it is often helpful to draw out and complete a table first.

The x values are fixed and the corresponding y values are calculated.

Example

Complete the following graph table.

Here the x values range from -3 to +3.

A = x2 when x = -2 so A = (-2)2 = 4

B = -4 like the rest of that row

C = 0 + 0 + -4 = -4

D = x2 when x = 3 so D = (3)2 = 9

E = 12 + 4 - 4 = 12

F = 27 + 6 - 4 = 29

G = 2x when x = 2 so G = 2 x 2 = 4

Now it's over to you!

Complete the following graph table by matching the correct values to the letters.

A = x² when x = -2 so A = (-2)² = 4 B = -4 like the rest of that row C = 0 + 0 + -4 = -4 D = 2x when x = 2 so D = 2(2) = 4 E = 3² = 9 F = 3² + 6 - 4 = 11 G = 4 + 2(2) - 4 = 4 How did you get on with your first question?

The best method is to write down your workings for each number, so that you can see where you went wrong.
