Algebra 2 CP Name _____________________ Assignment Graph the following functions and determine the domain and range of the function. Also, determine whether each function represents exponential growth or decay. 1. Growth / Decay D = ______ 2. Growth / Decay R = ______ 4. Growth / Decay D = ______ D = ______ 3. Growth / Decay R = ______ 5. Growth / Decay R = ______ D = ______ D = ______ R = ______ 6. Growth / Decay R = ______ D = ______ R = ______ Without graphing, tell whether the graph is growth or decay and describe the translation of the graph: 7. 8. 9. 10. 11. 12. 13-15 Use the following information. You deposit $5000 in an account that earns 3% annual interest. Find the balance after two years if the interest is compounded with the given frequency. Round answers to the nearest cent. 13. annually 14. quarterly 15. monthly 16. Due to the recent stock market decline your investments are losing value at a rate of 2.5%. If you originally invested $2500, find the balance after 3 years. 17-19 Use the following information. From 1990 to 2000, the population increased by 23.5%. The population in 1990 was 15,982,378. 17. What was the average annual percent increase from 1990 to 2000? 18. Write a model giving the population P of Florida t years after 1990. 19. Estimate the population in 2010. 20-22 Use the following information. You buy a new car for $22, 500. The value of the car decreases by 25% each year. 20. Write a model giving the car’s value V (in dollars) after t years. 21. What is the value of the car after three years? 22. What is the value of the car after five years? Rewrite the equation in exponential form. 23. 24. 25. 26. 27. 28. Write each equation in logarithmic form. 29. 30. 31. Evaluate without a calculator. 32. 33. 34. 35. 36. 37. 38. 39. 40. 41. 42. Find the inverse of the function. 43. 44. 45. 46. 47. 48. Match the function with its graph. 49. A. 50. 51. B. C. Graph the function and state its domain and range. 52. D = _______ R = _______ 53. 54. D = _______ R = _______ D = _______ R = _______ Answer Key 1. D = Decay 2. D = R= 4. D = Growth 3. D = R= Growth R= 5. D = R= Growth Decay 6.
