Hi

the idea is that You substitute the x-value in the function given

x	f(x) = 2x^3

-2	-16  = 2%28-2%29%5E3+=+2%2A-8+=+-16

-1	-2

0	0

1	2

2	16

+f%28x%29=2x%5E3+
x|f%28x%29
-2 |-16 ...+f%28-2%29=2%28-2%29%5E3=2%2A%28-8%29=-16+
-1 |-2 ...+f%28-1%29=2%28-1%29%5E3=2%2A%28-1%29=-2+
0 |0 ...+f%280%29=2%280%29%5E3=2%2A%280%29=06+
1 |2 ...+f%281%29=2%281%29%5E3=2%2A%281%29=2+
2 |16...+f%282%29=2%282%29%5E3=2%2A%288%29=16+
