11. Draw the graph of each of the following logarithmic functions, and analyze each of them completely. (1) f(x) = logx (2) f(x) = log x (3) f(x) = log(x 3) (4) f(x) = 2log 3 (3 x) (5) f(x) = ln(x+1) (6) f(x) = 2ln 1 2 (x+3) (7) f(x) = ln(2x+4) (8) f(x) = 2ln( 3x+6)
Complete the following questions on separate paper. You may approximate answers using a calculator. 1. The Richter scale is used for measuring the magnitude of an earthquake. The Richter magnitude is given by R = 0.67log(0.37E) +1.46 where E is the energy (in kilowatt-hours) released by the earthquake. a.
The formula y = logb x is said to be written in logarithmic form and x = by is said to be written in exponential form. In working with these problems it is most important to remember that y = logb x and x = by are equivalent statements. Example 1 : If log4 x = 2 then x = 42 x = 16 Example 2 : We have 25 = 52. Then log 5 25 = 2. Example 3 : If ...
Expand the following logarithms. Use either the power rule, product rule or quotient rule. Expand the following logarithms using one or more of the logarithm rules. Sometimes you need to write an expression as a single logarithm. Use the rules to work backwards. log3x2 + log3y . Use the Product Rule for Logarithms.
