THIS TEST:

Integer and Rational Exponents ; Scientific Notation
• Use properties of exponents to simplify algebraic expressions and write answers using only
positive exponents .
Convert numbers from scientific notation to decimal notation and vice-versa.
• Perform calculations for numbers given in scientific notation and write the answer in
scientific notation using the correct number of significant digits .
• Evaluate expressions involving rational exponents without using a calculator.
• Use a calculator to approximate a radical to a specified degree of accuracy.
• Convert an expression in exponential notation to radical notation and vice-versa.
• Use properties of exponents to simplify expressions involving rational exponents.

Inverse Functions; Exponential and Logarithmic Functions and Equations
Draw the graph of an inverse function if you are given the graph of a function.
• Find the equation of the inverse of a function.
• Sketch by hand and recognize a general graph of an exponential function f (x) = ax and of a
logarithmic function ; state the domain and range of such functions.
• Know the meaning of a logarithm and a logarithmic function.
• Evaluate expressions involving logarithms.
• Use the power property of logarithms to solve exponential equations.
• Solve equations involving logarithms by converting to exponential form.
• Use exponential and logarithmic models to solve applied problems.

TO PREPARE FOR THIS TEST:

Make sure that you can do all homework and worksheet problems.
Read your textbook, paying special attention to the Chapter Summary and Review at the end of
each chapter
Make sure you know all the important formulas and properties .
Do the following review exercises for each chapter, using your book and/or notes to help if you
have any difficulties.

Suggested Review Exercises
Chapter 1 (p. 97)/ 38 – 45, 48 – 51
