Cool-down Here are two definitions of the same sequence: Definition One: f(1) = 64 and f(n) = 12. f(n-1) for n 2. Definition Two: f(n) = 64 • (12)n-1 for n 2 1. 1. List the first 4 terms of this sequence. 2. Write an expression to represent f(20) 3. A person is trying to quit chewing gum. They decide they will have 64 pieces in week 1, but each week have half as many as the week before. The function represents the number of pieces of gum they will have in week. What is a reasonable domain for this function? Explain your reasoning.

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0
