If given concentrations of a reaction, and the balanced reaction. How do you find K and if the reaction is going forward or reverse?

Are you referring to a question in today's quiz? I think you can not find the K (equilibrium constant) if only the concentrations are provided because you do not know if the reaction is at equilibrium. Instead you can calculate the Q, which equals to k(forward)/k(backward) at that instant moment. However, you have to be given k(forward) or k(backward) to calculate the other one.
