How Do You Determine Values of a Periodic Function with Limited Data?

[Veronica_Oles]

Homework Statement

Find maximum and minimum values for the depth of h of the water
If a periodic function has f(2) = 1 and f(5) = 0 predict what f(8) , f(-10), and f(11) will be.[/B]

Homework Equations

The Attempt at a Solution

f(8) = (6+2)
= f(2)
= 1

f(-10) = (-6-6+2)
=f(2)
=1

f(11) = (6+5)
=f(5)
=0

I have the answers, I just am having difficulty figuring out why this occurs.

Not enough information is given.

Do you know the period ?
