Membership to a racket ball club has an application fee and a monthly fee that can be modeled by the function c(m) = 12.50m + 49, where m is the number of months of membership. the club is running a special in which the application fee is being waived as well as the first month's payment. this can be modeled by the function s(c) = c – 12.50.

1. a) an equation, b) a graph, c) A value chart. See image attached for examples of each.

2. a) Create a value chart and insure each x value has one and only one answer. b) Create a graph and insure the function passes the vertical line test.

3. See image attached. The graph presented fails the vertical line test and is therefore not a function.
