For this case we have the following equation:

\(d (x) = 15 + 0.5x
\)

Where, by definition, we have the following variables:

d (x): the daily expense per truck (in dollars)

x: the daily mileage

Therefore, the domain of the function is given by:

\(x> 0
\)

Equivalently:

[0, ∞)

Answer:

The input for the function includes all positive real numbers

option d.
