Question

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

Answer 1

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?

Answer 2

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

Answer 3

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]]
