Homework Help: Hepl with f(x) function

  1. Nov 20, 2008 #1
    1. The problem statement, all variables and given/known data
    the function decribed by
    f(x) = (2, -2<x<2
    = (0, 2<x<6

    and f(x) = f(x+8)

    Q1, what does the last equation mean in words?
    Q2, how do i sketch the graph of the function f(x) over 3 periods?
    Q4, is it odd or even?
    2. Relevant equations

    3. The attempt at a solution

    The rules of the forum are that you need to attempt to answer these before anyone can help. It just has to be an attempt. What would a function that satisfies f(x)=f(x+8) look like? Any opinions?

    Can you use those to find f(7)? Hint: 7= -1+ 8.

    It's period will become 8 (obvious).
    And determine odd or even function:
    if f(-x) = f(x) then even function
    if f(-x) = -f(x) then odd function.
