f(w,x,y,z) = ∑(1,3,4,6,9,11,12,14)

The function is:

A	independent of one variable.
B	independent of two variables.
C	independent of three variables.
D	dependent on all the variables.

Question 9 Explanation:

w and y are not needed to represent the function f. So f is independent of two variables.
