Topics

○ Exponential functions

■ General concepts (domain and range, asymptotes, etc.)

■ Writing equations from a graph

○ Exponential equations

■ Writing exponential equations from a word problem

■ Percent increase/decrease (less emphasized than on the test)

■ Plugging in to find a value, especially using a word problem

■ Using logarithms to solve for x

○ Inverse functions

■ Basic definition

■ Graphs: flipping x and y values (flipping domain and range, etc.)

■ Equations: solving for the independent variable, which becomes the new dependent variable

○ Logarithms

■ Logs as the inverses of exponential functions, domain and range, etc
