You cannot travel a negative distance. So the domain is the set of nonnegative real numbers. To be "nonnegative" basically means "not negative". The distance d is some positive number or 0. In notation form, the domain is d+%3E=+0 (the same as saying x%3E=0). In interval notation, the domain is [0,\infty)

The range is the set of real numbers greater than or equal to 100. This is because $100 is the lowest amount that it costs and that cost can increase based on the distance. The range can be stated as M%3E=100 (the same as saying y%3E=100). In interval notation, the range is [100,\infty)
