Algebra I - 2nd & 4th blocks

Study for tomorrow's Unit 4 test on Exponential Functions.  You will have to be able to identify the key characteristics of Exponential Functions: domain, range, asymptote, x intercept, y-intercept, average rate of change, type of exponential (growth or decay), base (< 1 or > 1), and end behavior.  Also review transformations.  Be able to identify the values of a, h & k to describe the transformations of the parent function and to write the equation given the transformations. Review compound interest problems and be able to identify the values of P, r, n and t in order to calculate the future value. Be able to graph an exponential function given an equation.  Below are the answers to the Unit 4 Study Guide which we reviewed this week during class.
