Final answer:
The function d(s) is based on the relationship between money spent on gas and miles driven, with 's' representing the amount spent and 'd(s)' the distance driven; it could be proportional or include a fixed cost.
The correct answer is none of all.
Step-by-step explanation:
The function d(s) that represents the number of miles Tyler can drive, where s is the amount he spends on gas, can take various forms depending on the relationship between money spent and miles driven.
If this relationship is direct and proportional, without a fixed cost, an equation of the form d(s) = ks where k is the rate of miles per dollar spent would be appropriate.
If a base fee or other fixed cost is involved, the function could take the form d(s) = ks + b or d(s) = ks - b, where b represents the fixed cost or base fee.
