How do you expand a logarithmic expression using the product property?
Identify products within the logarithm, then split the log into a sum of logs: .
How do you simplify a logarithmic expression using the power property?
Identify exponents within the logarithm, then bring the exponent down as a multiplier: .
How do you change the base of a logarithm to base 10?
Use the change of base formula: .
How do you solve logarithmic equations?
Apply properties to isolate the variable. Rewrite in exponential form if necessary.
How does multiplying the input of a log function by a constant affect its graph?
Results in a vertical translation (shift up/down) of the graph.
How does raising the input of a log function to a power affect its graph?
Results in a vertical dilation (stretch or compression) of the graph.
How does changing the base of a logarithmic function affect its graph?
It affects the 'height' of the graph, as all log functions are vertical dilations of each other.
