Question

F(x) = 2[x] how do you graph this?? any help would be great im stuck!

Answer 1

Give x a value, eg, 0, therefore y=2(0)
Give x another value, and so on

Answer 2

what are the brackets? is this just f(x) = 2x? Or are you trying to show absolute value or something?

Answer 3

i wonder if its a step function

Answer 4

its just absolute value

Answer 5

so the usual absolute value graph is a "v" with the point at the origin and a slope of +/- 1. Multiply by two, and it's the same thing except with a slope of +/- 2.
