8. Circuits. (10 points) Consider the boolean function of 3 variables f(x,y,z)=xyz. (Recall, denotes the xor operator.) Which of the following represents the function f ? Mark all that apply. yes no f=x((xy)(xz)) yes no f=xyz+xyz+xyz+xyz yes no public static boolean f (boolean x, boolean y, boolean z){ if (x \& y) return z; if (xy) return z return z
