The correct interpretation of the initial value in the given equation \( f(x) = -350x + 1,400 \) is:
The initial value of 1,400 represents the distance from your starting point to your final destination.
At \( x = 0 \) (which represents the start of your journey), the distance from your starting point to your final destination is \( f(0) = 1,400 \) miles.
