# Indonesian University Entrance 2015

**Algebra**Level 1

Hi guys, so this is my question from my last exam on SBMPTN 2015. It's an Indonesian exam to qualify students that wants to entrance Public Universities. This is the basic skill question:

a function states that:

*f(-x) = -f(x) for every real numbers*

and if we have

f (3) = -5

f(-5) = 1

what is f(f(-3))?
