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

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

**Example**

Complete the following graph table.

**Answer**

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

**A** = x^{2} when x = -2 so **A** = (-2)^{2} = **4**

**B** =** -4 **like the rest of that row

**C** = 0 + 0 + -4 = **-4**

**D** = x^{2} 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**
