Show all work and explain why it is/isn't. y O 34 2 41.14 4 49.7794 60.233 Use the given functions to answer the questions associated with them: 4. k(x) =12(1.28) 4. 1(n) =4.35(0.93)" 1-unit Change Factor: 1-unit Change Factor: 1-unit Percent Change: 1-unit Percent Change: Vertical Intercept: Vertical Intercept: 5. The population of Egypt in 2002 was 73.3126 million people and was 78.887 million people in 2006. Assume the population of Egypt grew exponentially over this period. Use these two data points to find the 1-year change factor for Egypt b. What does the change factor tell you, contextually, about the way Egypt's population was changing in that time period? c. Write an exponential function for the population of Egypt (in millions) for the years since 2002
