All points of the step function f(x) are graphed. On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is a closed circle. The right end of each segment is an open circle. The left-most segment goes from (negative 3, 1) to (negative 2, 1). Each segment is 1 unit lower and 1 unit farther to the right than the previous segment. The right-most segment goes from (0, negative 2) to (1, negative 2).

What is the range of f(x)?

−3, −2, −1, 0, 1

−2, −1, 0, 1

all real numbers such that −3 < y ≤ 1

all real numbers such that −2 < y ≤ 1

Hye ryung is the president of the local chapter of the american medical students association (amsa). she is organizing local outreach and informational meetings. at her first meeting there are five people present (including herself). every month after that her group grows by 5 people. a. how many members are in the group after 6 months? b. the logistics of hosting and feeding her group at meetings was more complicated than expected. the cost of feeding 5 people at her first meeting was $30, for 10 people it was $35, for 15 it was $45, and after 6 months all of the costs had added up to $100. write a function to model the cost with the number of people attending meetings. c. what connections can you make between the linear growth of the group’s membership and the increasing costs of running meetings?
