Part II Graphing Logarithms
Logarithmic and exponential functions are inverses
Graphs of Logarithmic Functions A. Sketch and analyze the graph of f (x) = log 2 x. Describe its domain, range, intercepts, asymptotes, end behavior, and where the function is increasing or decreasing. Construct a table of values and graph the inverse of this logarithmic function, the exponential function f 1 (x) = 2 x.
Graphs of Logarithmic Functions Since f(x) = log 2 x and f 1 (x) = 2 x are inverses, you can obtain the graph of f(x) by plotting the points (f 1 (x), x).

Use Logarithmic Functions A. EARTHQUAKES The Richter scale measures the intensity R of an earthquake. The Richter scale uses the formula, where a is the amplitude (in microns) of the vertical ground motion, T is the period of the seismic wave in seconds, and B is a factor that accounts for the weakening of seismic waves. Find the intensity of an earthquake with an amplitude of 250 microns, a period of 2.1 seconds, and B = 5.4.
Use Logarithmic Functions R = Original Equation = a = 250, T = 2.1, and B = 5.4 7.5 The intensity of the earthquake is about 7.5. Answer: about 7.5
Use Logarithmic Functions B. EARTHQUAKES The Richter scale measures the intensity R of an earthquake. The Richter scale uses the formula, where a is the amplitude (in microns) of the vertical ground motion, T is the period of the seismic wave in seconds, and B is a factor that accounts for the weakening of seismic waves. A city is not concerned about earthquakes with an intensity of less than 3.5. An earthquake occurs with an amplitude of 125 microns, a period of 0.33 seconds, and B = 1.2. What is the intensity of the earthquake? Should this earthquake be a concern for the city?
Use Logarithmic Functions R = Original Equation = a = 125, T = 0.33, and B = 1.2 3.78 The intensity of the earthquake is about 3.78. Since 3.78 3.5, the city should be concerned. Answer: about 3.78
