Consider the following boolean function of four variables $f(w,x,y,z) = \Sigma(1,3,4,6,9,11,12,14)$, the function is
= XZ' +X'Z
Therefore the result is independent of 2 variables
Answer is Option B
f(w,x,y,z)=Σ(1,3,4,6,9,11,12,14).
K-Map of given function -
f(w, x, y, z) = xz' + x'z
Ans- B. Independent of two variables.
