11. ### Verify These Games are Convex-Concave

I have to verify these games are convex-concave: a) f(p,q)=-(pq)^2 f(p,q)=-(pq)^2 b) f(p,q)=-(p^2-2p+1)(q^2+4q+5) f(p,q)= -(p^2-2p+1)(q^2+4q+5) I am a bit confused as i thought i was supposed to take the second derivative with respect to p, show it is positive then take the second...
