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.
Answer
Here the x values range from -3 to +3.
A = x2 when x = -2 so A = -22 = 4
B = -4 like the rest of that row
C = 0 + 0 + -4 = -4
D = x2 when x = 3 so D = 32 = 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!
