I think you meant so say

d(t) = v_{i}t + (1/2)at^{2},

which is distance traveled at constant acceleration a, with initial speed v_{i}, starting from d = 0.

The quantities v_{i} and a are constants. The independent variable is time t. Note that d(t) does not depend on final speed v_{f}.

therefore, would it make sense to say that the answer is choice Vf because it does not appear in the equation at all? If it helps, this is how one would get to the equation above:

you would have to combine these two equations to eliminate Vf and get the equation in the question.

delta d = 1/2 (Vi +Vf) delta t

AND

Vf = Vi t a delta t

_{f}, so the answer from the list is (3)._{f}is not a a variable in this problem. It is a constant.
