2. The Smashing Squash (or The Squash), is a band that regularly plays at the same venue. They realized that they could model the length of the line waiting to get into their concerts as a function of the number of years since they formed. a) b) c) d) When they rst got together the line was 6 feet long from that moment the line grew at a constant rate of 8 feet per year until the line was 100 feet long. At this point, the venue couldn't hold any more people and the line stopped growing. 15 years after the band formed, the venue expanded, and the line began growing at a. constant rate again, reaching a maximum of 150 feet 2 years later and then remaining that length. To the dismay of their fans, the Squash broke up after 20 years. Let. t be the amount of time since the band formed, in years, and let L be the length of the line measured in feet. Let J(t) be the length of the line in feet when the band had been together for t years. Then L = J(t). Note that J(t) is dened only while the band is active. How many years had the band been around before the line stopped growing the rst time? include units. What are the domain and range of J(t) in the context of this problem? Give a formula for J(t) that is valid on its entire domain. Hint: use a {immense-dened function. The invertible function 9(L) gives the amount of time, in minutes. it takes for everyone to get into the venue when the line is L feet long. For each of the following, either give a. practical interpretation, or explain why the expression or equation doesn't make sense in this context. (i) 9(J(2))=13 (ii) 9"(30) (iii) J(9(20))
