In the given equation \( f(x) = -350x + 1400 \), where \( f(x) \) represents the distance from the final destination and \( x \) represents the number of days traveled, the initial value occurs when \( x = 0 \).
Substituting \( x = 0 \) into the equation gives:
\[ f(0) = -350(0) + 1400 = 1400 \]
Thus, the initial value is 1400, which represents the distance from your starting point to your final destination.
Therefore, the correct response is:
The initial value of 1,400 represents the distance from your starting point to your final destination.
