how to make a xy table for the following greatest integer equation.

f(x)=2[x], g(x)=[2x], f(x)=-[[x]], and
g(x)=[[-x]]

thank you for the help

just list some x values, and their corresponding function values.

Not sure what [[x]] is
I think [x] is the greatest integer function (floor)
What is [[x]]? ceiling? absolute value?
x is the values you plug into like 0,1,2,3 but I'm confused how to solve when plugging in because of the greatest integer function value
greatest integer is easy. Take any value, and use the greatest integer less than or equal to that value.

[0] = 0
[0.4] = 0
[0.999] = 0
[1.11] = 1
[2.345] = 2
[1323.3423] = 1323
Watch out for negative values:
[-0.5] = -1
[-1.01] = -2
[-14.43] = -15

Still no idea what you mean by [[x]]
