Discrete Mathamatics (Floor & Ceiling Function in function)

  1. Jan 30, 2012 #1
    Ceiling = "{" & "}"
    Floor = "[" & "]"

    f(X) = [ 1/2 - {x/3}]


    How would I graph this function?

    Note: If the decimal is floors it will be rounded down , if the decimal is ceiling it will be rounded up.

    ~Thanks.

    When x = 0, y = 0. Trivial to verify.
    Look at [tex]0 < x \leq 3[/tex] Why did I pick 3?
    Then look at [tex]3<x\leq 6[/tex]

    Just keep observing what is occurring during the intervals.

    Would the first domain be ceiling or floors?
