function.

• Find the equation of the inverse of a function.

• Sketch by hand and recognize a general graph of an exponential function f (x)
= a^{x} and of a

logarithmic function ; state the domain and

**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 .
