Graph for y = x3 (x*x*x)
Take values of x from say 1 to 10,
Make data table
x = 1 then y = (1*1*1) = 1 (ordinates 1,1)
x = 2 then y = (2*2*2) = 8 ( ordinates 1,8)
etc.
Draw x (horizontal) and y (vertical) axis, select scales, install points and draw curve through points
(Note: known as an exponential type curve)

A cubic function.
x to the power of 6.
1 cm cubed = 1 cm X 1 cm X 1 cm 1 cm = .01 m, so 1 cm cubed = .01 m X .01 m X .01 m Therefore, 1 cm cubed = .000001 m cubed, and 243 cm cubed = 243 X .000001 = .000243 m cubed. In summary, multiply cm cubed by .000001 to get m cubed.
x^3 - x^3 = 0 Remember , whilst 'x' is an unknown value, that unkonwn is a fixed value. As a numerical example 3^(3) - 3^(3) = 27 - 27 = 0 The '3' is 'x' in this case
4.6 cubed = 4.63 = 4.6 x 4.6 x 4.6 = 97.336
