The success of a shopping center can be represented as a function of the distance (in miles) from the center of the population and the number of clients (in hundreds of people) who will visit. The data is given in the table below: No. Customer (x) 8 7 6 4 2 1 Distance (y) 15 19 25 23 34 40

2)If the mall is located 2 miles from the center of the population, how many customers should the shopping center expect?
