HL 4.3 - Logarithmic functions
SL 2.9: Logarithmic functions and their graphs: f(x)=\log_a x,\;x>0 , f(x)=\ln x,\;x>0 In the previous section you studied the basics of logarithms - how they are defined and how they operate. Now we will consider functions that contain a logarithm and focus on how they behave by looking at their graphs. By definition, logarithms and exponents are inverse operations if they both have the same base - one undoes the...
