Math 116: Chapter 4 Study Guide

  1. Match the exponential function with its graph. Eight parts. Look at problems 4.1.15-22
  2. Solve the exponential equation for x. Two parts. Look at problems 4.4.15-23
  3. Match the logarithmic function with its graph. Eight parts. Look at problems 4.2.47-52
  4. Solve the logarithmic equation for x. Two parts. Look at problems 4.4.28-36
  5. Match the function with its graph. Eight parts. Look at problems 4.5.1-6
  6. Rewrite the exponential expression in logarithmic form. Look at problems 4.2.9-18
  7. Rewrite the logarithmic expression in exponential form. Look at problems 4.2.1-8
  8. Simplify the expressions without the use of a calculator. Eleven parts. Look at problems 4.3.73-86, 4.4.37-42
  9. Find the greatest integer of a logarithmic expression. In English, that means to give the first digit of a logarithm. For example, the log 5.4 412 is somewhere between 3 and 4 because 5.43<412<5.44. The greatest integer of any value between 3 and 4 is 3, so the answer is 3. The greatest integer function is symbolized using the double bracket. See page 111 for a discussion of the greatest integer function.
  10. Write the expression as a sum, difference, and/or constant multiple of logarithms and simplify (if possible). Three parts. Look at problems 4.3.27-46
  11. Write the expression as the logarithm of a single quantity. Three parts. Look at problems 4.3.49-68
  12. Solve the equations. Give an exact answer. The problems have been designed so the answers can be found without a calculator. Pay attention to domain. Five parts. Look at problems 4.4.43-56, 89-96
